What is race sag?

Min weight limit 75 kg for all bikes - reduce some of trick riding and allow durability of bikes to come back in. Maybe adopt F1 idea of limited engines /frames per year etc, enforce 1 minder only - no mechanics - proper parc ferme after weigh in/practice. Like no stop idea Like combined round with a national series Rather than stating that organizers must have a large hard standing area minimize teams to one vehicle of a sensible size only!!!! Like no stop idea!!!! All riders bikes must be made available for sale after any round and at end of year - max asking price

As I believe minor changes 06 to 08. 09s different feel to steering and different exhaust. With all extra moving bits check for good oil/filter services

Cos I've not found a Map that gives the same smooth mid to top end as the Sains map? 250 to 280 is only a 10% increase so not a major difference but open to suggestions for a 250 map. I ride bottom gear majority of the time and like the rev and drag ability of the Sains map.

Been running Sains map on both of my 4rt over the last few years but had "otar5" map as a second map on 2 map PTB. I liked the initial softness of Otar map but love the mid top end of the Sains map. As had week off work thought I would spend a morning comparing maps and try to create a combined map. Listed all fuel and ignition variables from the 2 maps onto spread sheets so I could compare differences. Then working with the Sains map I altered bottom end values to that of Otar5, trying to ensure a nice linear transition. I think each map has 96 fuel values and 96 ignition values so had to compare nearly 400 points.(doesn't help when rev and % throttle opening intervals where different on the 2 maps) Probably changed 20 values each fuel/ign at the lower end of Sains map. Also did ease off some of the mid range fuel values as well as Sains map is heavily fueled. Used the various graph displays to make sure no holes or peaks had been created inadvertently. Then just a matter of downloading to bike. A quick play on the bike yesterday seemed to confirm that what I had intended had been successful -will see what weekend brings. PS - decided to call the map "Middle aged Sains Map" - Same model as current Sains but bottom end not so firm.

All Mont stands and brackets as far as I can tell are the same - 315/4rt. They are not the best but are serviceable if looked after. Having said the above the 4rts do seem better but appear the same design. They are relatively cheap to buy a new bracket so maybe that is the answer if your current one is US. I just take care where I and how I park the bike and have been know to put a spot of weld on the stop to bring the stand back to just past vertical. If you can improve it let us know.

Not sure drag going to be an issue when hitting a step flat out in 3rd with a 14stone rider. I think localised pressure is going to be the big issue. Mechanical advantage must mean that the PSI or KGMM2 at the actual bearing point must be big. Hence hardened bushes/needle rollers as std. Trouble is needle rollers are better suited to a some sort of rotation which is not seen in suspension. Good luck with experiment as good mods are worth while. I know some people offer sealed for life linkages - be interesting to see whats in them. Best solution I've seen was mono Yam - called grease nipples - grease every week - grit out, fresh grease in!!

Seem to recall cable can get wedged between frame and tank. Just put your hand under frame on left side when putting tank on just to pull a little slack in the cable to stop it getting wedged. 5 year since I had 315r but think this helped. Best of luck

spring is in master cyl - no external ones fitted that I can remember. Check links to pdf manuals elsewhere on TC to confirm

probably saw the the possibility of rain and didn't want to push the bike back to the start like last btc

Have posted elsewhere on BTC but agree totally with Woody. I love the Traditional trials rounds, I can also ride the odd S3 rounds without killing myself - especially if a clubman route is included so what ever happens with the BTC don't mess with the rest - top 15 or 20 riders might disagree but the several hundred others may agree.

I welded on new brackets and fitted 315r Mont footrests but you wouldn't want to weld to your nicely painted frame. I see there are bolt on footrest that give similar benefits. However fancy ally or titanium footrests in my mind are OK when new but allow no home refurb when welding is needed to raise then back up when they wear.

As a rider, enthusiast, official and BTC C of C I really don't know the answer. Scores from Sunday look spot on so congrats to Torridge who I know are a super keen bunch and have full respect for. However I think there are too many objectives to be achieved in BTC these days. Top boys want to be pushed and have a chance to pull a mistake back - even in Expert A and B Clubs want it to be feasible -good entries Onlookers want it to be what they want!! I think the format the last few years has been ok but not sure if this is sustainable in the future. The current ability of top riders and bikes means that given enough time the good riders will get through any section that does not physically knock them off. If you mark out a tricky traditional style section that could take the odd mark if ridden in a flowing manner will be broken down into 20 hop and stop bits and then be told the section is too long for 90 second time limit. I think with stop allowed its down to big stuff (and yes they do go backwards), or no stop with all its possible observing issues but with less extreme sections. - I guess take your pick!!

Tips for a first timer - get as fit as you can and then some. Practice riding as fast and as hard as you can for 2 hours then when you are worn out do it it for 2 more hours and then when you are absolutely worn out carry on again for 2 more hours. See if you can ride a few local time and obs trials. Also ideally watch it the year before you enter to get a feel. Its a special trial so don't underestimate it. Unlike anything else but absolutely amazing

I do like my 4rts but this is a bit of an anticlimax. Most of weight saving is probably from X lite tyres. Milling aluminum don't save much. Could have at least fitted flat tanks as std. Maybe have to be 2013 for the reverse cylinder motor then!!!!

I like std gearing but ride most things in 1st. Not sure about R1 chain but the std Montesa chain is good value. Normally get a year out of mine.

Agree Air filter oil does not evaporate but solvent carrier does when you use spray filter oil. It seems to be the build up of the solvent in air box that upsets things. When stopping the bike with the kill button is there a programmed stop? - ie fuel off or does it just stop the spark like a basic carb bike?

so why does a lightly oiled filter put straight in mean the bike will not start but same filter in 1hr later and no issue. Stop the bike by stalling it an not best starter. Stop bike with kill button and starts every time. Bike won't start, flick throttle and press kill button. Starts next kick

Maybe you mate didn't get bike warmed up and stalled it rather then stopped with kill button and fouled plug or similar. Be interesting to get bike running and warm and try old plug back in. As a side note I put very a very freshly oiled filter in mine Friday night (rushing a bit) and bike was a pig to start first thing sat am. Was maybe firing occasionally. This I find is very common with solvent type filter oils. I just kept turning engine over slowly with max throttle and then reset and normal start. Fired up eventually and been fine ever since.

Have you tried a new plug?

Steve - no offence taken or even considered. Anyway the club doesn't do the results so that was at least one thing I didn't need to worry about yesterday. I think we'll adopt the F1 strategy next time we have bad weather and sit in a portacabin drinking coffee until it dries up. Was there anywhere it didn't rain yesterday.

you know we are a bit slow in Wales!!!!! I think alex would of been glad if he was on a beta as for the 2nd year running Sherco number 1 rider had bike problems

Personal experience on 2 05 4rts Genuine 06 Montesa clutch are about

There is wet weather and there is what we had today - when the venue is limited to the streams/rivers and banks it is limited as to what you can change at the last minute(section are not just stuck in on the Saturday morning). The sections where changed yesterday after practice with all riders invited for their comments and all the riders requests to change sections where met before we left the venue last night (and the riders knew it was going to rain). Sections where further eased today before the start and eased again on the first lap when the champ boys got to some of the sections. But when the rivers and stream go into flood condition not sure what you suggest can be done. Best we could do was cut to 2 laps on safety grounds. Easy to pick fault but we are all volunteers and the putting on a BTC has probably involved nearly 900 miles personally traveling to the venue to mark out, attend practice and the trial over the last 5 weeks don't want to contemplate the number of hours put in.

Tell you tomorrow at the finish
