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.

Hi...My TY250R mono starts 2/3 kick and ticks over fine, once I kill the engine walk a section and go back to kick it over it wont start, I've tried leaving the petrol on/off but no joy, anybody else experienced similar ?

Hi, Can anyone advise if the TY250R Final Drive Guard Protectors are still available, Sammy Miller no longer list one in the catalogue ? also are there any wide footrests currently available that fit to the original mounts ?

I have a 1991 model TY250R with the plastic tank. I have attempted to put new decals on it but within a day they have formed hundreds of bubbles underneath. Anyone have any suggestions? Is there something I can prime/seal the tank with to stop the vapour seeping through?

I know some people frown upon it, but I'd like to convert my TY350 Mono to a twin shock. Has anyone done it and can pass their wisdom on to me?

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,

Hi what is the best castor based 2t oil and the easiest to get hold of? and what ratio to run it at on my tlm200 (aircooled) p.s i want to get the the castrol r smell but i have read that its not got for trials bikes cause it clogges up the piston or something like that? thanks sam

Hi,looking for some advice, The bike started running erratically and lacking any power eventually dieing with no spark at all. I have changed the coil pack and still only sparks intermittently, on pulling the side cover of the left of the bike I noticed a lack of a gasket and that a lot of crap/dirt had got in.l Could this be the cause or does anyone know better? Got one of the lambretta coil packs of ebay on advice from a forum seems okay. I have a yellow wire which isnt connected to anything at the moment. What size flywheel puller do i need i have already got quite a collection but not small enough for this. Thanks in advance for any help or advice.

my mono keeps dying, seems like fuel starvation, after a bit of bouncing(not that i do that sort of riding) but it creates the problem it just dies, kick it over and off it goes again, just replaced float valve which everything pointed to, but still have problem any ideas gratefully accepted

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 !!!

Does any one have any advise on main bearings as it got to be that that clanging away as i rode it yesterday for the first time and it clanged all day but ran ok .What i would like to know as in a month time im going on a weeks trials holiday .Do they just get noisey are do they aventually go bang .Also what kind off expense am i looking at too have a engine rebuild and any recomendaions who could carry out the work any advise would be welcome. thanks peter

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…

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?

I'm thinking of going the aircooled mono route. I'd like - 2 stroke, disc brakes at both ends, electronic ignition, not too exotic so that spares are available. Which is best? I've seen a Montesa 310 and a Fantic 305 for sale but don't know anything about either of them. Any info appreciated? I've also seen a Honda TLM220R - this only has disc on front - do later ones have F & R discs. My thinking is that I can ride the air cooled mono class at the "classic trials" and have a go at "modern trials" on the same bike. Any info/advice greatly accepted.

Im in the middle of a restoration and have 2 questions that i need help with please. I want to plate alloy. I want a bright / chrome like / polished plating. Whats the brightest and blingest that is available to average Jo? I need steel tubing , 200mm long / inner 17mm / outer diameter 20mm. This is for internal hub wheel spacers. I'll need to machine a step in them to slip inside the bearings.Im sure you guys will have come across the type before. Where can i get this tubing from - any recommendations ? Thanks
