    I'm sure this question has been answered loads of times but what's the current view on which oil to use in the front forks? SAE 30 or Auto Trans Fluid. All suggestions appreciated Paul Mac

    Would love to now more about this type of bike spotted at the DK Mansell trial last Sunday, there were two of them riding round...a brief chat with one of the riders, he mentioned tha the motor was made in China (a Honda copy?) 200cc and very sweet sounding indeed.

    Looking for a cheap pair of trials shocks. The cheapest I found are $115.00 from Speed and Sport. Any one found any cheaper? This is for a bike that will be for sale soon. For a keeper I'd get the Falcons.

    Hi, after mounting a new timing chain my TLR 200 has a huge base engine knocking noise What I did: Changed the timing chain cleaned out the centrifugal oil filter on the right side After the rebuild refilled with oil, started the unit and: the noise from the chain slack was gone but a huge knocking noise from the bottom end came on. The noise is in sync with engine speed and does not fade away like after the refill of a dry engine. Sounds like an engine w/o oil pressure What I checked again: Timing: OK crankshaft bounce ( in case I bent the crank while blocking it to get the rotor nut out) 0.1 mm on rotor: OK gears I blocked with a mild steel piece: No bent/br…

    Just found a Kawasaki KT250 (age un-known), toying with buying and restoring it. The bike has obviously been stood for many years, and there is a hole knocked into the right-hand casing that i can put the tip of my index-finger through (this could be repaired or replaced), but saying that, the bike does have a good compression and looks as though it is complete, even has the original fenders and not much wearing-off of the decals. Also there are two cables going into the top of the right casing, one's the clutch (?), but whats the other ? Lastly, what year/years were they made, what is spare's availabillty like and are there any web sites for these bikes. Thanks in adva…

    Have just acquired a rare aprilia 50 trials of 1981 vintage..... (similar to a fantic 50). It's got the obligatory minarelli motor but the carburations a bit, erm, fluffy! -runs all nice at tick over, ok on full throttle but not so good on the rest. Carb doesn't have a pilot jet, just a main and an emulsion tube. Anybody got a carb of japanese origin (approx 15mm) they would care to pass on for a good price......? Andy. ps. or 125 honda 4 stroke motor.......

    Not much that's newsworthy right now up here as were in the grip of winter snow at my house, there are no trials for a month or so, so I'm thinking about project bike. Just out of boredome I thought I'd post a pic from the "Hodaka Days fun trial" which will be coming up on it's third year this coming June in Athena Or. As you can see the terrain is not the most challenging thing you've evr seen. I am one of the guys in charge of laying out the sections for this event which promises to become a classic. Every year more people are building Hodaka trials bikes. The estimate for 2004 is thirty riders. With this in mind I am planning to build some sections in advance, perhaps …
