andyj007 Posted March 19, 2012 Report Share Posted March 19, 2012 Have just acquired a nice tlr 200 1983. It has had some work already complete. Powder coated frame, fork angle, foot pegs, steel clutch plates etc.. The engine was rebuilt with new rings and bearings late last year, have receipts. The engine sounds sweet, starts first kick but does smoke a little, say giving it a few revs from a tick over and for a few mins from starting cold. Could anyone give me a nod in the right direction? Is his normal for an older bike, or assuming the rings and piston are good, then I'm guessing might be the valve and seats? Many thanks Quote Link to comment Share on other sites More sharing options...
andy m Posted March 19, 2012 Report Share Posted March 19, 2012 Common on tlr's is valve guide seals, I have had 2 and they both needed doing. If after the bike has been stood for a while you start it and it smokes but then clears it will be them. Engine needs to come out. Valves will need lapping in and fit new seals.

andyj007 Posted March 19, 2012 Author Report Share Posted March 19, 2012 Cheers. for the reply . a good place to start then. will it be ok to use in the meantime? or is it causing damage? i will have some spare time in a few weeks but would quite like to get out on a few trials first.. is it possible you could list all the items required for this works.. whilst i can use a spanner I think i may just get all the parts and get some assistance . I have a manual, and whilst my mechanical skills are ok, I strip and rebuild forks and seals, ive never had an engine to bits apart from adjusting some tappets on my triumph spitfire 1500!.. Is this something i could tackle myself? or is it beyond my skill sets.. many thanks Andy Quote Link to comment Share on other sites More sharing options...
andy m Posted March 19, 2012 Report Share Posted March 19, 2012 Ride as is if you like, just keep an eye on the oil level. It should calm down after starting and warming up. You need a top end gasket set, some come with seals and some don't. may be worth asking these if their set comes with seals.... http://www.ebay.co.uk/itm/NEW-HONDA-TLR200-TLR-200-TLM220-TLM-TOP-END-GASKET-SET-/350406189754?pt=UK_Motorcycle_Parts&hash=item5195d622ba#ht_888wt_754 As for stripping etc it depends on your ability, they are quite simple, if you have a manual even better. As I say engine needs to come out, familiarise yourself with the valve timing inc marks before you pull it apart. You will need a valve compressor to remove the valves from the head.

craig10 Posted March 19, 2012 Report Share Posted March 19, 2012 (edited) If you're going to the bother of fitting new stem seals, get genuine Honda ones if they're available. I've found on my Honda single trail bike that the pattern ones give up quite quickly and then you're back to square one.

totalshell Posted March 19, 2012 Report Share Posted March 19, 2012 if you can change a fork seal you can sort your valve guides out. read the manual well before hand keep it close to hand, clean out the workspace and work methodically use your phone to take photos for reference if needs be. from the manual you chould be able to work out what you might need. befor eyou start this though make sure you ve done all the easy stuff.. clean plug, carb, air filter, air box make sure carb is set right than start pulling stuff to bits..

andy m Posted March 19, 2012 Report Share Posted March 19, 2012 Find out if the seals were done when the engine was rebuilt. Check all the above and do an oil change first, it may be due,use a good oil. don't worry about a little puff of smoke when cold, it won't hurt.

andyj007 Posted March 19, 2012 Author Report Share Posted March 19, 2012 The engine had a full rebuild two years ago and a ring and noisy bearing done recently. The previous owner does not know if they were replaced then or not. So let's assume not. He's still digging all the receipts out for me. I will order the gasket set and genuine seals tomorrow. I can't see it carb related as its a white blueish smoke, and smells like its oil. Carb/ air filter issues normally on four stroke make running rich therefore I would expect discharge to be black smoke...correct? Will have a read of the manual tomorrow.

tlrmark Posted March 20, 2012 Report Share Posted March 20, 2012 Only use genuine Honda oem valve seals, aftermarket seals are inferior. Its too much work to replace them and have them fail prematurely which I have seen happen many, many times. Quote Link to comment Share on other sites More sharing options...
tlrider Posted March 20, 2012 Report Share Posted March 20, 2012 When you say 'aftermarket seals are inferior' are you refering to the blue viton seals available on ebay? Quote Link to comment Share on other sites More sharing options...
andyj007 Posted March 20, 2012 Author Report Share Posted March 20, 2012 i have been told that most cheaper aftermarket seals use nitrile rubber, the oe parts are viton.. a far superiour material for this use... therefore if the ebay ones are viton they may be ok.. i have just ordered all original honda parts to be on the safe side it was only a few extra pounds anyway.. cheers andy Quote Link to comment Share on other sites More sharing options...
