I've just noticed that with the fuel tap left on for half an hour the tank has emptied it's fuel into the airbox which I guess would indicate that the floats aren't shutting the fuel off yet there doesn't appear to be anything wrong with them or the shut off valve?
I hadn't used my Sherco for nearly a year until a week ago when it started up fine and I ran it at our club practice ground for about half an hour. Then after my son dropped it, it started missing when opening the throttle and wouldn't idle so I packed up and went home to sort it out.
I emptied the tank and found about an egg cup worth of water in the fuel tank, this I cleaned out. I removed the (Delorto) carburetor and found the plastic link pipe between the float bowl sides had a big hole in it, I guess where it had been rubbing on the intake manifold. I stripped the carb, cleaned it in my ultrasonic tank, blew it out with compresses air, dried the metal parts at 50 degrees C in the oven, replaced the plastic pipe, fitted a new fuel pipe and inline filter, new spark plug changed the gearbox oil and put it all back together with fresh fuel and 2 stroke.
It started second kick, ran for a minute or so but wouldn't idle and then stalled. I couldn't get it started again and on investigation have found that it's flooding badly. There is a spark at the plug but the plug is saturated and the air filter box has a cupful of fuel in it. With the tank removed I have got it started by kicking it over half a dozen times with the throttle fully open but it won't keep running.
I've taken the carb off and checked that I've put it all back together properly and that the rubber end of the choke mechanism is intact. When I stripped the carb I counted how many turns from fully in the gas and idle screw were and have set them back as they were. The idle screw was 4.25 turns out from fully in and the mixture screw was 3.5 turns out from fully in.
I'm stumped as to what to look at next, can anyone advise?
msm are the insurers of choice if you wish to do road trials.. 4 trials a year and you ll be in credit against using on the day insurance. carol nash insure all my bikes simply and cheaply.. on reg numbers or frame numbers.. also unlimited aa call outs.. against an aa recovery/roadside policy which now limit to 5 call outs per year on a std policy..
im about to enquire with msm about the possibility of cars whilst on long distance car trials
Thanks totalshell, I'll give Carole Nash a call too.
Hi Deryk, yes I guessed the steering head angle and gearing would probably be different, as for the weight a fair bit has been done and I can do more. But at the end of the day if I get the carburation, timing, clutch and controls etc setup, I'm sure the bike will be more capable than my abilities will push it to.
I'm 15 minutes from my clubs practice ground (Milton Buzzards) so I'll be getting plenty of use of it there and I would like to have a go at some of the road trials like the Arbuthnot as we were discussing in the other thread.
I've since found MSM Insurance who offer cover for trials and enduro bikes in competition usage and spoke to a really helpful lady called Jan, so competition cover problem solved. http://www.msminsurance.co.uk/trialsenduro.asp
Thanks Deryk, yes I was aware that it's a converted road bike when I bought it and I believe the price reflected that. Had it been a genuine 16 MC/16 C I don't think I would have been able to afford it, so I saw it as an affordable (for me) way into pre-65 trials, (I also have a Sherco 290 and a Bultaco). I'd be interested to know what the differences are between what I have and a genuine version that make it only "look vaguely like a trials bike" if you could enlighten me? And am I wasting my time using it in club trials?
I've just bought a 1959 AJS 16MS in trials trim, I believe it would have originaly been a standard road bike. I just called Footmas James who I have another classic bike insured with and they say they won't insure it because it's a trials bike! When I asked them if it would make any difference if it was an original factory trials bike they said it wouldn't as they don't insure trials bikes!
Can anyone recommend any insurers who will insure a classic trials bike?
I need a pair of alloy mudguards for my 1973 Bultaco Alpina and was going to order a pair from Rickman as they can supply a pair for £70 plus postage. But they have two different widths for the rear mudguard, 5" "C" profile and 5.5" "D" profile. Am I right in thinking it's the 5.5" wide one I need? And has anybody bought these mudguards from Rickman?
Thanks for the heads up on the 320, why do manufacturers offer a 4 stroke? Is there any advantage over a 2 stroke?
When's the best day/time to come down the club site Nigel? I'll give the club contact a ring at the weekend as I'm back up to the bike show at the NEC again tomorrow.
I'm in the Milton Keynes area and am looking to get back into trials riding after a break for over 20 years! I used to be a member of the Milton Buzzard club when they had their practice ground at Elfield Park and I owned a couple of Sherpas. I sold my last Sherpa when I started racing my Rudge in the VMCC but now I'm 50, I thought it would be a great way to keep fit!?!
I popped along to the new Milton Buzzard ground last Sunday and it looks great, all I need to do know is pay my subs and find a bike. This is where I'd be really grateful of some advice.
I've been looking at Sherco 290s (I guess it's a Bultaco thing) but am wondering if I should be starting with a 250 or less? I weigh 14 stone at the moment (hoping this is going to go down to 13 stone!) but in effect I think I'll be starting again as a novice. I also saw a 4 stroke Sherco 320 at a good price but are these unsuitable for a novice? My budget is £1,000 to £1,500 for my first bike.
