Fair enough, although not to use google as at least your first port of call these days is a bit ignorant

Well at least i knew what the bike was! You however seemed to be more interested in trying to tell the original poster he didnt know what year the bike was, when in fact he was right and then attempted at some stupid reason for it being green. "Honest thread", yes, but only if we disregard your silly posts After some digging around apparantly they used the green on some 74s, 172s and the enduro 75/125

Then why say it was 1972 when the 172 didnt come till 75?

Looks like a 172, and if you google search 'cota 172' a green one pops up. THats the only help i can be sorry....

Which only comes into effect when the fuel level is lower than ideal, resulting from inadequate float bowl volume. Its the combination of both

I thought gguk prepared all their bikes, thats why i was a little scathing, if they dont, then i totally take it back. His throttle style probably requires a different setup than the other riders lol Yeah exactly, reving through the rev range is never a problem, its always that mid throttle hold than brings the weakness out. I would really love to try one of the trun racing larger float bowls. While i agree the jetting is a cause, i think after long drags or hill climbs its the lack of fuel in the float bowl is the real problem. A fix with the dellortos used to be to fit a larger fuel jet, but as far as i know there is no easy fix on the keihin. I first seen raga with the larger bowl a few years back and he always run with it. I've seen price with it fitted once or twice as well and it rang true with what i experienced. Long hills climbs, get to the top and its running out, and if the bike is at any incline it makes it worse. I fitted a jitsie bowl nut because it has a slightly larger volume than the standard keihin nut and i think it helped. I never did price a trun float bowl, has anyone else?

You can mention all the names you like, or how many world champs the guy has. All i know is that every time i hear jack price riding a section his bike is knocking. Go watch the BTC video from hookwoods if you like, it was particularly bad there. Fast forward to 37:50, if that isnt a bike underjetted, i dont know what is. Its so bad you could possibly say its overheating or there was water in the carb, but that isnt the only section let alone the only trial ive heard it do that

A shallower taper from the same diameter surely means weaker....

That doesnt mean its right. Hearing one of their bikes recently, i didnt realise there was a fuel embargo

Its a 125 and its 16 year old, both of which should not be ignored. Your mixture IMO isnt far off, could maybe drop it to 60:1, but without knowing how throttle happy you are its hard to say

No matter how bad you think you are, there will more than likely be someone the same level as you or possibly lower. Slow full lock turns using the clutch can never be mastered too much!

Pressure is inversely proportional to area, so via extrapolation a zero disc area (100% air) will have infinite pressure. You could be on to something

Only if you dont count electricals towards reliability!!!!

Check this out pmk https://trials.com.au/forum/viewtopic.php?t=5066 As you probably know the sy motor is largely a tyz, never seen a decomp on a tyz before, but going by the barrel casting it looks like a standard fitting to me, weird. Someone else obviously thought it necessary

I had a 07, 08 and 09 sy in the Uk, the only modification being to rotate the stator virtually right round to fully advanced. Granted this did make them a bit harder on the kick, but compared to shercos and 300 ggs of the time definitely easier to kick over. Ive heard of some countries having lightened flywheels, so if youve also heard of higher compression ratios, then that would definitely explain it. All mine were uk models, so cant comment. Maybe they just had their heads machined down a little more, couldnbt see them changing much else. A lighter flywheel certainly wouldnt help in kicking over compression PS Its been 9 years since ive kicked one so my memory may be off. But my dad who was 60 at the time could start it easier than any other modern bikes ive owned

Use motul transoil 10w40 myself, never had any problems

I understand your desire to lower it, and im not going to tell you not to. I have a few bikes myself with jake brakes so know what theyre about but IMO the sy is far from a high compression motor, they were a clubmans favourite for years because of it. You could start them in slippers!

Either hand it to rossi, or take it away from those other guys! Sometimes i think they should be doing better

I would be more worried as to why your sy has too much compression. These bikes are one of the easiest of modern bikes to kick over, mainly because of their short stroke and long kickstart. Has your ignition timing been advanced?

No engine is designed to run while sucking in water and if youve a wet filter, thats almost a guarantee

Looks a clean bike for the age

It sounds like you like to take good care of your bike, especially when its new which is good to hear. One thing worth doing is having a look at the rear shock linkage bearings, the dog bone bearings. Ive seen them come new greased and come new dry. Takes 5 minutes to look by removing one bolt. Definitely worth it, you could be riding round with dry bearings

I dont know why, do you?

He doesnt necessarily need to compete, hes got such a lead he could miss a round and still have 10 points over Raga going into the final round, but we dont know what is written in the rules. He may have to compete every round to count in the championship. Also, at the end of the day, you get points even for finishing last!! So even if he turns up, tries the first section and retires he will get at least a point. Without disrespecting the other riders he could quite easily ride without stressing himself too much and finish above last. He did the same a few years back at the outdoors with an arm in a sling. People thought he was mad at the time and he only went and won the round!

+1 for sidis from me, although i bought them before the stylemartins came on the market. Would be interested in trying the latter. For me, gaernes arent what they used to be 10 year ago
