mont315

I would say 50:1 for an older 2 stroke engine but after saying that I use TT in my montesa 315 @ 80:1 and use the same mix in my strimmer and not had any probs

if your carb is a PHBH 26CS http://www.dellorto.co.uk/merchandise/products_details.asp?PartNo=R4173&CategoryID=2&PartsectionID=20

just my luck both are hex and worn so cant undo either one, looking at the engine diagrams it look's to me its the outer of the two will wait and see what else is said

hi peeps just got an aprilia 320 and wanted to change the gearbox oil, but looks as if there are 2 drain plugs on the bottom of the crankcase, any idea which one it is

I use s3 hardrock's they are really comfortable to stand on and good grip, comes with 2 washers so they can be spaced http://www.bvm-parts.co.uk/index.php?route=product/product&path=123_31&product_id=818

I rebuilt mine this time last year with all genuine bits from sandifords, eg mains, seals, piston kit, gaskets total bill was £514 most expensive part was the crankshaft they don't do a conrod kit so had to have a new crank @£195, barrel replate was £140 the rebuild was worth every penny in my opinion they are a fantastic bike love mine to bits as mentioned in a previous post http://www.langcourt.com/page16.html for replating barrel

yes it does make a difference its basically a straight though system (no baffles )in the rear silencer

google bikersrest .com for a practise ground £5 a day, something there for everyone to ride

I've had one for about 3.5 years now absolutely bullet prof engine but keep the oil changed regular as the cam runs in the head not on bearings and once a tear clean the oil spinner out, as for mods the main one is repositioning the footrest down and back about 25mm as for altering the steering angle unless your riding on harder routes don't bother. I've fitted 400mm betor gas shocks to mine and I find they work well for £100 shocks plus being longer than the standard 200 ones it raises the rear a little making the steering a little better, I use 5w or 7.5w oil in the forks and 10/44 sprockets. yes there are better t/s bikes out there but reliability wise you better a TLR http://www.trialscentral.com/forums/gallery/image/3549-tlr-200/

im not sure 4stroke, problem being bob is getting on age wise and he haves trouble remembering all that he has done over the years but it sounded like it was all 250s, funny thing was the first trial I rode the bike I just happened to park up next to bob as he was unloading I said look what I got his words were "bugger me" I aint seen that bike for 20 odd years that was chris suttons bike!

bob gollner himself confirmed that this was ridden by chris Sutton, as it has been mentioned before the rear shock was made by falcon, bob told me that the head was fitted with bigger valves and a hotter camshaft but the gears were standard 250 and not changed unlike the 200 were.
