Unless it's realy tired , (in need of minor overhaul) I've never heard of a 315 being a slacker in the power dept. start with the basic's and make sure it is in good tune ie plug , clean air filter , timing set correctly no air leaks(vacum), carb clean , float level corect, ect. ect. make sure it's as it's suposed to be before looking for mods.... imho...
I'm a fairly well seasoned competitor who lost track of trials for almost
30 years !!!!
And finding my way back after 3 wives and a whole bunch of other B.S. has been the best thing to happen to me in quite a few years !!
But a newbie guide would be a wonderful thing !
And iff we could get all the dirtbike buying public to understand that almost
all of the best enduro, motox , and even roadracers ride trials in one form or another to sharpen their skills and practice bike control fundamentals !!!!
Glenn, and you do , do a great job too.......................
I remember being maybe 10 or 11 and just finished a NETA event in cape cod (I think?) and watching Don Sweet ride down the length of some loose telephone poles just laying on the ground ... I just had to fire up my trusty tl125 and try it to no avail. I could get maybe 5 feet down the log and then front wheel would be on one side and back tire on the other !!! and mind you , the poles were only a foot in dia. or less... Don and his dad were always the niceist folks , He was #1 in new england for the 2nd or 3rd year at the time...
Wish I never left N.E. for CA. when I was young, I would have stayed in trials and might be able to actually ride a bike now !!! But thats life and now I'm in my 2nd childhood and I just wanna have fun ! and compete a little .!!!!!
Thanks Don wherever you are...

And around the same time my brother rode support in a world round in new england (got a full page picture in cycle world magazine , ratty shirt and all, but it was a classic new england picture of him in a stream !) and I saw lane ride more than once , HE does truly know how to work a trials bike...
And Bernie was there too. Good Times !!!! Those three were my idols when I was a boy. and none of my freinds understood what trials was , I wish the japenese had stayed in trials like they were then , It would be a differant sport now , at least here in the states.!
Lane; what is the full title of Bernie's book ? And a ? for my memory banks ,
When did all the hopping start ? cause I got away from trials right about the time Bernie became champ or the begining of that year... and at the time I don't recall hopping at all. And it was all slow and controled no stopping at
Minor family emergancy so I had to cancel out *#*&^*$##!!
And Alan your going to have to come to a ITSA event at Ginders ranch after I get some NJB Trikshoks on my 'NEW' 240 pro so you can apriciate what the old girl can do ! I do owe you a ride on it and we have got to meet !
But I won't be able to get out there until october the way things are going
I too just started competing again after a 25 or 30 year hiatus ...
And yes at my first modern event I got enough 5's for a whole season , but in my defense the bulk of them were for cleaning a section on the wrong line ! or just completely blowing the section . ( I was excited like a little kid !)
But it was the different observers that made the day for me , I received the most congratulations and encouragement from them the whole day long ... They all made me feel good at the end of the sections even when I did something stupid !!!
How could you be ungrateful for them spending the day watching everyone else ride and enjoying themselves !!
I used two HK2020uu brgs on each side of the swingarm and drilled the arm for greasefittings, then used orings for seals on the inside ends of the the swingarm . just be careful where you drill the holes for the fittings . The shifter side zerk has to be at the bottom fo the tube near the weld or it will hit the engine case , and the chain side one has to aim right at the countershaft . I used miniture angled zerk fittings drilled to mount between the 2 brgs , and when you install the brgs , leave a small gap between the casings so grease from your fitting can get thru . and ounce mounted you have to file the end of the fittings off on the inside of the brg. hole so you can get the brgs in far enough with a slight gap between them over the grease fitting mount hole.
I got the brgs. from www.vxb.com , and if your shaft is gouged up you can get a new one from Atelier BMZ in france, www.bmz.fr , a great source for all kinds of old bike stuff ...
It sounds like alot of work but was actualy quite easy and well worth the effort to have a smooth ,long lasting swingarm pivot...
Just reassembled my 240 pro yesterday with new double needle brgs. in the swingarm pivot, and can actualy see the stock marzocchi's flex upon compression !!!! It works 100% better with new brgs. but I need new shocks.
Has anyone tried the new NJB trikshok W/ the spherical brgs in the eyelets instead of rubber bushings yet ! looks like the hot ticket to me !!
So I shouldn't get it and massage a tl250 motor into it ????
Can I get a suit like that to match my fantic !!!!!
