Wavy discs Why ?
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

Compression Release
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

Compression Release
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

Compression Release
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!

Rossi 3rd in Qatar.
Either hand it to rossi, or take it away from those other guys! Sometimes i think they should be doing better

Compression Release
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?

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

New TXT 300 Pro Questions
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

Bou to Compete at X Trial This Weekend in Paris?? Really???
I dont know why, do you?

Bou to Compete at X Trial This Weekend in Paris?? Really???
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!

BOOTS!
+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

Dt250 piston rings
Its an expander ring, pretty common in 2 strokes, especially yamaha. Most people leave them out, however if you want to fit it it goes behind the lower ring

Toni Bou Sidelined with 3 Broken Vertebrae
Ive seen this a few times from him, no minder, trying to do the section all on the back wheel, and did notice what you point out. While i suppose we all appreciate his showmanship, I guess the bravado caught up with him a little

Jet washing bikes
But its virtually impossible to power wash a bike without getting some water into the airbox, resulting in a wet filter. I would not want my bike running as the filter gets continually wetter and wetter
-
Toni Bou Sidelined with 3 Broken Vertebrae
Either section design or lack of protection has to be at fault for this one. While square edge concrete blocks arranged at extremely difficult angles does produce big bike lifts , an accident like this was long overdue. If youre gonna ride sections like that, back protection is a must, or if you know riders have limited protection marking sections with a lot of square hard edges is inadvisable

Jet washing bikes
Just dont directly point the pressure washer at the carb or flywheel cover for prolonged period. The amount of people i see that point the jet right at the carb and hose the life out of it just to remove every speck, and then complain they are always getting water in their carb. Ive also seen people power wash a bike after an event with the engine running. Dont think ill ever understand the reasoning behind this

Jet washing bikes
I actually dont start mine after i wash it, as im careful enough to know i havent got water in. Anytime i have condensation has formed on the slide, entered the carb, resulting in a carb dismantle. This was with a dry airbox and clean filter so where it comes from im not too sure. People will say im talking nonsense but its happened with me a couple of times now. I wouldnt leave it more than a few days though
