  1. I'm building a Banvill 197 with a 9e engine that ran fine 20 years ago, currently waiting for bottom end to return from alloy welding. But looking at the top end & comparing it to photo's of the Greeves it was previously fitted in I'm concerned about the length of the carb inlet, it's 3 inch long plus a 3/8" fibre spacer see photo. with the air filter I've bought I don't think it will all fit in the frame loop. I have no problem shortening the inlet but just wondered if anyone had seen one as long as this as previously I had Villier's carbs on other engines.

    If you are going for their 'yamaha' conversion the pushrod will need shortening (and the mainshaft)

    No keeping standard just fitting modern plates, it worked when last used I just expected a ball after I took the pushrod out. The pushrod protrudes out the shaft by 1mm (0.040 thou)

  3. Should there be a ball bearing behind the clutch pushrod  & when arm is pulled in how far should pushrod protrude from end of shaft see photo. Not ready for re-build but making a shopping list of parts ready for Villiers Services order, thanks.

  4. I'm recreating the bike my Dad built for me in the 60's I have a standard bantam 18 incch rear wheel currently fitted with a 3 inch road tyre my question is will this rim accept a 4 inch wide tyre or do I go for a 3.5 tyre. Swing Arm is a Triumph factory trials wide.

    I've been running twinshocks and Pre 65 all my life but have recently bought a 270 Rev 3 and upon investigation the rim is corroded on the inside, not as bad as a twinshock Honda or Air cooled Yamaha if you know what i mean, around all the spoke nipples and i think this is why it kept going down. I've cleaned it up as best i can but cant get into around each nipple without a wheel rebuild and is so would probably just have to fit a new rim. I've been told by a couple of people that you can run a tubeless tyre on a tubeless rim with a tube but without security bolts. Now from past experience with pre 65 and twinshocks, ok they were tubed tyres on tubed rims, this would be a recipe for disaster and a valve ripped out.

    Is this correct and has anyone here run a tubeless tyre on a tubeless rim without security bolts succesfully ? I will be running approx 4 p.s.i. teh same as on my other bikes btw.

    Cheers  

    Drill the rim & use security bolts they are not  overly expensive to buy.

    You seem shocked by this ? Stop allowed means you can stop, feet up or down. And for as long as you want, so long as there is no section time limit, nor p*** off the observer and fellow competitors by overdoing it

    Senior riders seem to like a rest in latter stages?

    Some more context of what your talking about might help?  World round level, local club, video on the internet, etc.?

    Without the context its hard to say for sure but it really depends on what rules are being observed.  As walkertrials indicated if its a stop permitted event most rules I have ridden under let you if your hands are on the bars and engine is running.  Some of other variations of stop allowed might be something like a stop is fine with feet up or something like that, if its a no-stop event then it should be a 5 because of the stop foot down or not.

    If you are in fact talking a no-stop event, witch it seems like you are, then a rider not getting called a 5 when they did stop with a foot down would be an error on the part of the observer, often because of misunderstanding the rules or not being focused on the rider when it happened, but would of course have been a 5 by the rules.  

    So hope that helps.  :thumbup:

    Can someone explain to me how a foot on the ground when stopped is not a fail?

    It's only a fail if the rider doesn't have both hands on the handlebars or the engine has stalled, so any observer giving a 5 in a stop permitted event are affecting the results. ACU reg TSR 22

  9. I agree Intotrials it is percieved as being boring but so are snooker & darts and many others but they seem to get plenty of TV time, in my area we have had two new groups of riders take up trials one from Enduro & one from MX the MX riders can't believe what the experts can get over and the Enduro group say they wasted 10 years of their lives before trials so we must doing something right.

    Absolutely not!!!! Maybe for the youths, but id rather have the £5 it cost for some fake chromed plastic trophy than the actual trophy itself! Those things aren't even recyclable, straight to land fill in my house.

     

  11. I'm not on about sponsors for events more the awards you win, clubs now days don't do the Premier, first & second class awards the majority run club championships and only the winner of that receives an award ( there are exceptions obviously)

    The purpose of sponsorship is to make money for the sponsor.  The fishing contest prizes mean more entrants so more people paying for boat space, more bait sales and so on.  Since most trials are run by clubs who make very little if anything from entry fees and have limited capacity for numbers of entrants trials is not an obvious place to spend marketing budget.

    Sponsorship for a big event that brings in spectators like the cancelled Anglesey event is a better bet if you are looking to get companies to part with their profits.  I think it is a shame we cannot attract enough people to come and watch stuff like that.  Also why only Sheffield for the indoor trials?  Can we not attract enough people to other venues? 

     

  13. On a recent holiday to Scarborough I spotted an advertisement for a Sea Angling competition entry fee £5 prizes of from £200 down to £40 & £50 for largest fish. Trials & most other motorcycle sports pay a minimum of £15 entry and much more for speed events yet give out very few awards. I know we have insurance costs to take into account, some years ago I attended a local car rally regional status & drivers could sign on when using certain products tyres, oil etc and be in line for a bonus for a good result I'm talking modified road cars not WRC. You would think at National level trials the suppliers could give a little back to unsupported riders.

    Yes, It's been in the family a long time, and I must say nobody had much complementary to say about it! However, I am never going to be a good enough rider to worry about the bikes capabilities, it's certainly still better than I am!

    I know it's never going to be super competitive, I am just looking to do a few subtle modifications to improve things a little.

    Just make it safe to ride ie footpegs etc then ride it as it is it looks a Great little bike. As for front forks if they are too soft try thicker oil & some pre loaders on top of springs just a simple bit of tubing of the correct size will suffice.

  15. Quick update son has swopped bike I am going to record dates I replace wheel bearings. Thanks Basil for the images of pair of quality bearings with dust covers removed showing 1 was packed with grease the other bone dry. My conclusion crap manufacture.
