Having repacked my middle box ive still got a knock on the engine it seems to knock on the top of the stroke so im totaly baffled as there is no play in the big end or small end so all thats left is the piston to replace even though it looks ok . Ive read where a dt250 or a it250 piston will fit as they are the same as a ty250mono piston but a lot cheaper if so is there a certain year for each piston that will fit any help would be appreciated as im totaly baffaled !!!

Hi, Sorry but I cant find any of the previous postings about TYR front brake improvment by using YZ shield, Will ask any of you who have done this conversion, what year(s) of YZ front shield is working with TYR front hub? Cheers,

Having just spoken to birckett motorsports about a knock on my ty250mono it now apears it could be down to a blocked middle box.I wonded how do you go about cutting it open and has anyone done this and the knock and had good results. cheers peter.

I am looking for some kickstart gears for a 1990 mont 310 same engine as 309,307 ect anyone any idears ?????????? please dont say sandifords

Both front and rear wheels on this Mecatecno im working on have spacers inside the mag hub which hold the bearings apart when the wheel in tightened up. You know the sort , its quite common. The spacers slot inside of the bearings and stay in place that way , other wise they would rattle around inside the hub. The wheel spindle is 17mm thick. The spacers that slot into the bearings increase the internal bore diameter to 21-22mm. I need bearings with this internal bore i cant seem to find them anywhere are quite a bit of searching. My only other option is not to slot the spacers into the bearings.........but how do i keep them in place????. Any ideas Here's hoping ther…

Hi all, Could members advise the best gearing option for a TY250 mono (standard motor ) run solely for trials use?

Hi have nearly finished my TY mono rebuild . I've found a few problems on the way & would like to discuss them. My bike has a YZ 250 front brake plate fitted & iv'e had to machine a extended torque lug for the fork leg/ brake plate,anyone else had to do this? I also found that the carb had had a few DIY mods on it that didn't work very well.Corrected this by adjusting the float height to 23mm with the float tang just seating in the float valve slot, next fitted 42 pilot jet, highly vented air box lid, 145 main jet & needle back in the std position , air screw 1, 1/2 turns out. Bike now starts easily & runs like a top. Plastic petrol tanks don't fit very we…

It looks like all the previous TR34 owners have upgraded or broken their bikes as they have stopped asking questions! Therefore it is my turn to ask a newbie question. I've not done an oil change on my 1989 TR34 yet and I have no idea what oil to use. Reading other threads has left me bamboozled. I know I need 800cc gear oil as it states this on the Beta website. What is the best grade oil as I don't have to worry about having a Beta with a dodgy hydraulic clutch? Also I'm currently using up an old Motul 2T oil at about 70/1 with the expensive shell high octane petrol. The trusty Beta website says I should use Semi Synthetic so I was looking at either the PJ1 or Si…

Wrighty called me this evening and mentioned that he is short of a Garelli and a Moto Gori trials bike for his show next year. There are a number of themes to the 2010 show and Italian Twin shocks is one, he would be very interested in speaking to anyone who has a nice example that they might like to display. Pete
