zippy

check your ground, I helped a guy get his Sherco running the day after he washed it. He rode it for practice, washed it, and the next day at the event it wouldn't run. Cleaned the ground attachment at the frame and all was right again.

those I ride with keep trying beer and liquor............. not sure how effective it is. We shall continue further testing

within MOTA (Michigan Ontario Trials Association) we have 6 Clubs, each club hosts 2 events per season. For a rider to be awarded season championship points they must work 2 events per season. This is how we get the majority of our observers, the members of the club will set up, run, observe their 2 events for the season. and then you ride the other 10. Season championship standings are determined by your best 8 rides. It seems to work pretty good. But you do not have to be a member of one of the clubs to ride the events. You will get a trophy that day (provided you finish in the top 3) but you will not be awarded season championship points for the year end awards.

I use a tree, rock or a log.......... if none of those are available, I have leaned it against a buddy's bike. Or just lay it on the ground, that's her happy place anyway. Spends enough time there

Reed valve is located between the engine and the carb. the valve portion is inserted into the engine. While the Keihin carb in my opinion is better than the Dellorto PHBL, the Dellorto is NOT a bad carb. as with any carb, keep it clean so it can do its job properly

Clutch Master Cylinder

I believe the pressure plate bolts are 6mm - 12 point

Can confirm

Looks like the Torrot website is down as well

My RatTY 175 arrived like this: And it now Looks like This: There will be tweaks that happen for quite some time yet, but she can be ridden and enjoyed. And that was the goal.

Good luck, hope it is sorted quickly

I think you may have shift drum issues, if that is the problem, this will require splitting the cases. that pin looks a bit like part no. 13 in the photo below. source: http://lewisportusa.com/manuals/gasgaspartsman/04partscomplete.pdf

I think you may have broken the Top Hat, (gear selection spring unit) the cross bar is sacrificial and breaks before the shaft. Just remove clutch cover and clutch basket (one bolt in center) and you should see it

RatTY 175 runs! getting much closer to being able to take for a ride.

A local rider has one, well local (ish), he rides our events. anyway back to topic at hand, he has stated that he has has quite a bit of mud accumulate on the top of the swing arm but never in the sides. The day I got the look at the bike was an event my club was hosting and it was a mud fest, and sure enough I did not see any mud in the sides of the swing arm. As for the potential boot damage............. I don't know one way or the other

RatTY 175 is starting to look like a trials bike, not exactly a pretty one. But some of the ugly ones are the best ride.

We even have a pack for those

Adjusting the Eccentric screw may help this condition. https://www.youtube.com/watch?v=G55FU27Z9bU or may be bent shift forks.....

I just spray the outside of the filter. the oil is propelled by CO2 so it comes out rather cold and really stiffens up the filter. This makes is difficult to fit the "cage" inside the filter without possibly ripping the filter. So I will gently massage the filter to warm it up, which in turn gets the oil to even out in the filter. when warmed up, give it a good squeeze to release excess oil and good to go.

Is there a 'timing" hole in the flywheel? 2nd picture looks like there is a hole in the upper portion of the stator plate that a rod could fit into if there was a corresponding hole in the flywheel, in order to time the ignition. I may be wrong.

Getting closer to having RatTY 175 finished

Finally started getting RatTY put together. I have an engine now. Took these two tables of parts.......... And turned them into this:

There is also an online manual http://trialsport.com.au/TY175/
