Hi guys me again!! So after all my euphoria at finally getting mt TR1 to run, I turned her off, went back to my manual to see what checks i should do, oil pressure etc, went to start her again and got the strangest noise i ever heard, the starter didnt seem to be able to spin the engine, then would huff it over half a turn then make a whiny noise again! I took off the left cover (i will drain the oil first next time!) and removed the starter, checked the brushes etc, and checked the starter gears and throw lever etc etc, all seemed in place and ok, re-fitted everything and nothing has changed except for now sometimes the starter just spins on its own, doesnt even engage. I have checked various websites and this seems a common problem, but i'm not a technical man and some of the "fixes" seem pretty detailed. Does anyone know, in simple terms what I need to do?? Thanks as always for your great help Andy

Ah the mysterious blowback problem, well I would love to tell you that with all my technical knowledge and mechanical skills I fixed it, but the truth is I just did what you said, checked, and re-checked, I took the carbs off again and cleaned them, again, I cleaned every single bloody connector on the wiring loom I could find, I swapped the coils over, no difference, so it wasn't that one, and I re-set the cam timing, although it was fine anyway, so the truth is I don't know!!!

Hi all, First of all thanks to everyone who has helped, I finally got my TR1 started!! She fired eventually and idled great, no exhausts, flames shooting out!!! When i stopped her and tried to re-start her, the starter motor (i think) was making a whiny noise, then chugged the bike over a little, then whiny noise again, like it was trying to spin it but couldnt! Any ideas all you amazing guys?? Thanks in advance Andy ps, does the virago exhaust fit the TR1 the 535 or the 920 maybe? struggling to find an exhaust for her

Hi all, Finally got my TR1 to fire and run, for a little while, she was idling ok (no exhausts on so flames shooting out!!) i turned her off, but when i tried to re-start the starter motor didnt seem to turn the engine, just made a whiny noise, then turned a little, then whiny noise again! Any ideas guys??

It's a v twin and its the rear cylinder thats blowing the carb off, twin carbs, one for each cylinder, I have checked and re-checked the valve timing and the rocker gaps, these seem fine!!

It is sparking fine, but not firing, and as it turns over it blows the carb off its mounting rubber!!! I cannot see any smoke, or smell anything, maybe a little petrol but thats all, I am using unleaded will that make a difference??

Hey all, Thanks drewpy and yoda for your replies regarding my TR1 blowing back through the carbs, I have checked the ignition and the coils are the right way round, someone suggested it could be the TCI unit, electronic ignition i think? If this is the case then the bike is getting scrapped because I can't afford another one!! Is there any way to re-wire the bike without electronic ignition? Or a simpler way that may remove the TCI unit, or a cheap replacement for it?? I need all the help I can get as this has been holding me up for months now and I'm starting to lose the will to finish it, would be a shame to scrap it now but getting to the end of my patience and bank balance! As usual thanks for any help you guys can give me Andy

Hi all, I have finally got my 1981 TR1 back together (almost) the wiring loom is on the floor but connected(!) when i try and start the bike it spits back through the rear cylinder carb hard enough to knock it out of its rubber socket!! I have checked the cam timing and the valve clearances, and these are fine, the carbs have been cleaned and appear to be fine (i'm no expert!) but it wont fire, I have spark, and have checked the HT leads are wired up correctly. Also the bike turns over quite slowly although the battery is the correct one, and new. Any help anyone could give me would be really appreciated!! Thanks in advance Andy. PS Thanks drewpy for your advice, but still a non runner mate!!

Hi all, finally got my TR1 back together but it wont start, turns over and blows back through the carbs, these have been taken apart and cleaned etc and look fine, any ideas?? Thanks in advance for any help. Andy

Hi, Need a little (more) help with my TR1, the piston rings are firmly welded into the pistons, and pistons in a poor state. Does anyone know where i can buy replacement pistons and rings? will xv1000 pistons fit, mine are 95.0 mm according to the haynes manual Thanks for any help you can give me Andy

Hi all, just wondering if anyone knows the law on this, I have a TR1 (in bits) and when rebuilt did not plan on having a rear brake, is this legal? Thanks in advance for any help

Hi mate, thanks for reply, been working overtime so sorry for delay. Engine is on floor, that is my bench \yep still has oil and yep checking not seized, any ideas where i can get a gasket set? I agree about the throwing away, i meant not use it but it will stay in my garage along with the other bits not used, thanks again for your help you are truly a genius!!!

Hi all, just me again hassling you all, gonna post some pics of my wreck soon but need some more advice, my TR1 has a control unit for the wiring, can i junk this? i have a wiring diagram from the internet for a 1986 virago that a guy posted and looks good, but first i just want to turn the engine over, how can i do this? the engine is complete but on the bench as the bike was a wreck when i bought it i couldn't turn it over, can i do this with a fresh battery and a few wires? \i know i must sound like a nob but this is my first project and its from the ground up so i need all the help i can get!!!
