  1. You need to turn detective. Anything can fit anything if you have enough cash. doing it for sensible money is the skill.

    I have Aprilia wheels in my TDR250, with a rear sprocket from their 750 twin.

    In my case i felt from the specs i could find it should fit and worst case i could just re sell them so long as i bought for the right price.

    As far as it goes forks are a pretty generic distance apart. Not to the mm but its roughly  6 inches or so for the wheel and maybe another 2 for the spacer and spedo drive at the front so front wheels are not too bad. Newer bikes dont have a spedo drive and switching braking systems completely can be complicated and may need the full legs then you have the issue of length and spring rate too.

    Rears again are pretty similar if you break it down. this is more like 8 to 10 inches plus spacers. Wheels are the same set up, cush drive and hub.

    The skill is getting the wheels centred, cush drives are easier to machine to line up chains and are relatively expendable for the most part.

    Its easier to fit top hat sleeves in wheels with bigger bearings than sort smaller or weird sized bearings, so fitting wheels from a 750 to a 400 will be easier.

    Not forgetting ofc, its a 125, keep your cash in your pocket for your next bike would be best. But then i never followed any of that and have modified every bike i have ever had. 

    Spent a bloody fortune on the current one.

  2. Smaller valves and softer cam timing will also work with smaller tbs for better torque. s the FZ is the sports variant and likely to race, a manual cam chain adjustment weighs less and is more reliable, if more labour intensive.

    Go to Halfords and buy their box spanner plug remover usual sizes are 5/8 inch and 13/16. That way you don't have to grind down a socket. Just remember that box spanners are thin walled and will slip if you go gorilla on them! The cost is about £12 for a box spanner set.

    Agreed, but many people do go gorilla on plugs for some unknown reason, or worse put them in dry, we all know thats a bad idea from our own personal spark plug. 

    The first time on my v max i could not get enough force on the box spanner in the toolkit so had to get a bit serious. They came out but cracking them off was scary. 

    Who does plugs up that tight?

     

  4. On my vmax i have a socket i have ground down to fit better. There are only a few plug sizes, check on the bench that the plug fits the inside of the socket you have then grind it down till it fits.

    Not scientific but works. There must be a socket that fits, not wanting to cast doubt on the nay sayers that called for a new head. The blindingly obvious fact is, someone put the plugs IN. They would not have done that without a socket.

    Thanks Snakebite68.  I'm getting to the end of my rope with the damn thing now. Soaked it in oil, WD40, paraffin, heated it, but it won't budge.

    I'm very tempted by the Blackwidow exhaust too, but even the cheapest option is more than a third of the cost of the bike 👀.

    I'll  keep trying.

    I wonder if a halfway house solution might be an option- anyone tried drilling some holes in the blade, or cutting the bottom half of the blade away ? Can you tell I'm clutching at straws here ? 😁

    You cannot look at it from a numbers game, the bike as is, its a boat anchor. All its good for. If the rest of the bike is good and has years in it and you plan on keeping it for a couple of seasons then selling, 300 quid (plus can) is not the end of the world. You will get some back in improved resale by being able to prove no exup issues.

    If you were undecided on spending that on a new fairing panel against mending the old one, fair do's. But an exhaust, i would have bought it already.

  6. Commuting to london i think i would take the r3 of the two. 

    The r6 will be a very frustrating bike to ride in built up areas with heavy traffic. Constantly resisting the bikes need for speed as they come alive as it were quite high in the rpm.

    The r3 being a twin will give you a more relaxed trip and being able to use much more of the engine will be a better ride.

    Real world on real roads unless your being a complete arse neither bike will be any quicker outside of a trackday.

     

    Depends if you can cope with all the "oh you should have bought....." from the spectator gallery.

     

    In my opinion, for a city commute, an old divvy600 or fazer for 500 quid would be my choice for city/commuting work. Putting miles on it wont matter, will scrape 50mpg and if you fall off on a slippy roundabout in the rain. Who cares.

    Many thanks for the reply's appreciate it

    Have removed coil and tested, Primary Resistance is a small amount out at 2.7 (Yama manual says 2.16 to 2.64) however this is measured when its cold, and as Finnerz said I have only had problems when the engine is hot 

    Secondary resistance and plug cap all checked out ok, I have gone ahead and ordered a new coil, hopefuly this will fix the problem, will report back. (coil on a 15 day delivery time )

     

    Regards

    What about the high output, did you check the lead and the cap/plug. Coil dont normally 'just die'. especially being a single it would be gradually worse intil it died.

    Something simpler, check the wiring, earths to the engine in particular. Ig switch too.

    Let's get some dates up, I can't do weekends 14th or 21st of May but after that I can do most weekends. A long weekend is enough for me Camping but Devon/ Cornwall sounds great. Unless there's any other suggestions.

     

    Can't do the 21st weekend either. 

    Other than that just got to see what I can get from work. 

    Will call that pub merv highlighted and see what they cost. For end of May.
