Is George Spence in Fife ? Have you a tele' no. Will contact him and see what he says, I think he built the wheels originally. I'me using 20/50 and changing it every 2 - 3 trials.
Chain / tyre clearance on my B40 is minimal, I dont think the rear whel can be dished enought to give adequate clearance. Has anybody put a spacer between the sprocket and hub, then made new axel spacers to effectivly move the wheel away from the chain by a corresponding amount ? There is plenty of clearance to the right of he tyre. While I'me picking your brains, I've noticed that if I leave the bike with piston at TDC that it doesn't wet sump as quickly, is this something to do with where the oil pump positon in its stroke ?Thanks in advance for any thoughs / observations.

HI, its a bit of shame this is my first post as it could be bad news.... lol. Anyway i fitted a new throttle cable to my 2002 315r, only to find out that when i started it it was too short. The bike instantly went to full revs and must have stayed there for between 2 - 3 minutes before the petrol ran out of the carb. I had the tank on so i couldnt get the spark plug cap off. There were other things i could have done, i know, but i was paniking!! Anyway, nothing went bang and cyclinder gaskets are still intact, just a bit of steam from the coolant reservior under the tank. I put the old throttle cable back on to make sure the bike would still run, which it does thankfully. I took it for a blast up the street and it seems ok but i still have doubts until I can test it on some sections which i know how much power i need to use, if you know what i mean.
The bike isnt normally ridden with full revs, so it was probably a good clean out, the plug looked damn clean anyway!
What i need to know is could this have caused damage i dont know about and what should i look out for? And if this has happened to you please make me feel better and tell me what happened to your engines....
Cotter pins are fine once you get used to them. I use a tube with a hole large enough for the pin to pass through. This tube has to be the length / distance from your kick start to the ground (with the bike standing vertically. The idea is that as you hit the threaded end of the cotter pin, the forces are transfered to the ground rather than trying to bend the kickstart shaft. Use a bras drift or similar , and something like a Thore hammer, which gives a good solid thump. Replacement cotter pins can be bought from a pedal cycle shop. Normally I start the pin moving with the nut still attached, but undone till it is flush with the top of the pin, this stops you damaging the threads. Hope this helps. Ross
What steps are you guys taking to prevent this? Currently, the thropttle cable, clutch line and kill switch all get squished when the bars are turned full lock to the right? Rerouting the cable doesn't work as they are too short.
Thanks for the help.
You could buy a kit to make up a longer cable. (www.trialsbits.co.uk amiungst others.)
The forks on all the Jap twinshocks let them down, too softly damped and too softly sprung - unless the rider weighs about 10 stone.
I'll be trying a KT in a trial sometime soon and I'm interested to see how it rides. A brief ride on it so far suggests it isn't as bad as people say but time will tell.
I used to go to a classic trial in France each year until it fell victim to the green twats. One year a Swiss rider, Jack Aebi turned up on a standard KT250 that had been in a barn for years, it was original, even the shocks. He won the trial so they can't be that bad.
I respect what you are doing Michael, I will tell you that judging from my distorted eyeballs, I am not sure that all thing totally line up on my modern bike!
I have two theories,
1- The Spanyards really do not care!
2- The theory that certain neglidgable offsets may actually lead to some added stability could be true.
As you never really feel it when riding?????? The brain just adjusts, it seems?????
I have to agree with copemech, based on experience riding other peoples bikes which always feel like the bars are twisted etc when you get on, and yet within a few seconds you really dont notice. Just my opinion.
The TL125 had many faults, but it was my first bike, got it new from Edgar Bros in Edinburgh. Had many many hours of fun on it. It was very economical, even with lowered gearing, and nice and quite, enabling me to go places where I shouldn't have been. Have never been on one since, mostly because I think it wouldn't live up to the rose tinted memories !
60t sprocket improved it off road, but made little difference on road !
Lanarkshire are running trials Sat 6th Sept start 13:30 & Sun 7th Sept start 11:00 am. Todholes Farm, Fintry. Travel time from Edin approx 1.5hrs. To late for entry but you could have a look and observe if you want to meet riders. www.lmcc.co.uk
If anyone watched Charlie Boorman & Ewan MacGregor when they got a BMW welded the ABS etc didnt work afterwards because they didnt disconnect the various electrics !
Did anyone practice in Blackford Quarry (completly off limits now) probably late 70's early 80's ? It was a great place and very popular at the time. If the name sounds familiar to some , its situated on Blackford Hill , on the opposite side to where the SSDT finished before it moved completly to Fort Bill.
In my humble opinion, its got to be the modern 2stroke oil. I have a 20 odd year old bike, head has never been off it. Run it on 32:1 old fashioned 2 stroke, yes it does smoke a bit, the rest of the problems reported when using these ratios of oil just dont matter to me.
