Hi All Have recently bought myself a Triumpg Trophy 1200 4 cylinder hence username. It has been slightly cafe racered with clipons etc and fairing taken off. I aim to improve it as much as can, just extended Loom so CDI/igniter sits under rear seat instead of being strapped under lower yoke !!! Looking to find out improvements etc can make. Individual air filters performance exhaust and suspension. All done on a ver tight budget so will take a while and all done by myself DIY style So going to be picking peoples brains etc
most people seem to say the original airbox is better than individual filters, some fit k&n filter inside. hi by the way. I have a 900 sprint
Hi and welcome to the forum. There were a few Speed Quarto's built back in the day with the 1200 engine and from what I understand one or two of them were put in front of John Bloor at the time suggesting that these should go into production. This did not go ahead and a year later the Bandit 1200 came out. I do know where one of these bikes is and have been nudging the owner in the direction of selling it to me one day. With regards to the bike there are a few things to look out for, first thing you should do is check the valve clearances as these tend to tighten up over time. Also the ignition pick and the coils can cause issues as well so they are worth keeping an eye on. With my bikes I always but a fuel additive in the bike to try and keep the carburettors from getting blocked up and also the pilot jets are very prone to this. I would also advise for you to make sure you have a good battery as a half dead one could lead to the dreaded Sprag Clutch Replacement which is an engine out job and is rather expensive even if you do it yourself. If the bike still has the original organic brake pads might be an idea to replace them with sintered ones as they stop the bike a lot better. There are also a few other good bits with regards to spares ect on this forum so I hope this is of help. Cheers Steve.
Hi Luckily previous owner has had shims done last November and it`s only done 265 miles since also had coils, ignition pickup allreplaced last year. I also think it needs either cam chain sorting or adjuster looked at and carbs balanced as does`nt seem to be as smooth as should be. This is why i like it though as am a bit of a tinkerer so enjoying sorting these little problems out.
Have a look at the cam chain blades as they sometimes cause an issue and may need replacing. With regards to the bike running a bit rough, as I said before it might be worth pulling the carbs out and having a look at the pilot jets, also check the intake rubbers as if they are perished they may need replacing. If you do take the carbs out take the throttle cable off at the handlebars (if that makes sense) as they are next to impossible to get off and on at the carburettors and put a small bit of grease on the lips of the inlet rubbers as they are a bugger to get back on without doing this. Cheers Steve
Hi Had a look at inlet rubbers and they do look perished, will start it then squirt a little easy start in to see if bike revs up. If it does then shows that rubbers have had it. It has done 68,000 odd miles so these things need looking at. Loks like I`m going to be busy on e-bay
See if you can buy September's Classic Motorcycle Mechanics magazine as there is some very good articles on restoring early Hinckley Bikes in this issue which I think you would find very useful :upyeah: http://www.classicmechanics.com/
QuadumphUK, I haven't been on the forum for a while, so feel like a newbie myself. I purchased a 2000 Trophy a couple of years ago and enjoyed it for the summer. Love the power/torque and the smooth running BBBB. Recently sort out the carbs, rebuilt them, and all new rubber. Seemed to have solved the issues that I had been experiencing but during my last ride it started missing, one cylinder then two, until it quit completely. Had to trailer it home. One coil did not meet spec so changed out the pair. Checked the air gap on the magnetic pickup and found it to be a little tight, 0.03 mm not sure how to make the adjustment on that, doesn't seem to have any room to get any more clearance? jb
Thanks QuadumphUK, I don't know how I'm going to get that gap, the gap I have measures 0.03 mm right now. I've tried with the screws loose moving the pickup to get a larger gap but as soon as I tighten the screws it goes right back. ?
Welcome to the forum, QuadumphUK. You're close to correct. It's not only a good forum--it's a GREAT forum! If you can't get your questions answered here, you probably can't get them answered. Welcome aboard.
You just put feeler gauge between sensor and crank pickup to keep the distance. Bit like gapping a spark plug but not bending anything just keeping the distance to what you want
Goops,, guess I need to start checking the dates! Sorry. But welcome anyway--even though you've been on the forum way longer than me.
Yes, tried that, loosed the pickup, inserted the feller gauge and tightened the screws, but after that the gauge is pinched and after removing the gauge and checking the gap it is still the same as when I started, 0.03 mm.
Use a .04 gauge then tighten and re check it might just tighten up to .03 or try .05. So on and so forth until when you tighten and recheck it, it is .03
