that would explain the lack of confidence in the front end of my bike i obviously have the wrong pressures in my tires!!! i was beginning to think it was pshycological but if i have the wrong psi in my tires it does make alot more sense. have bought and paid for my new tires now and have opted for the bridgestone bt021 will see how these handle (at the correct pressures of course) when they arrive. went for these instead of the michelin ct since i dont intend on taking my bike on a track and the bridgestone according to reports has allegedly got a bit more durability on the centre contact part of the tire and is still pretty good on the edges for road use altho is known to overheat on the track so this will probably suit me better. many thanks for all the constructive feedback especially regarding tire pressures didnt realise bikes run so high a pressures. all part of the learning curve i suppose and hopefully some one else will read this post and learn from this too.

ah the old story of tire pressures, what is the recomended psi for a 600 thundercat as i really dont have much knowledge in these matters. i always run high pressures in the car when doing trackdays so on the bike i have put rightly or wrongly 32psi in the front and 34 psi in the rear. ( i dont use the bike on track so road psi settings only please haha) i have a sneaky suspision there will be alot of negative comments been hurled at computer screens when people read this but on the positive side i havent fallen off and still manage to get it leaned well over on bends. the bike came from the dealer with 32psi in the front so didnt feel the need to change this as i presumed this would be correct and im always more nervous about losing the front end so left it well alone.

im about 2 weeks away from needing a pair of new tires have seen a pair of bridgestone bt021 at the price of £158.00 incl delivery then obviously fitting on top of this. they are to be fitted to a yamaha thundercat 600cc. i currently run the bridgestone bt020 but the rear has flat spotted in the centre and the front doesnt give me much confidence when pushing hard in the twisties. has anyone got any reviews on the bt021 good or bad i want to hear all comments. also for another 20 pound i can get the michelin 2ct. are these worth the extra 20 pound or is it just another marketing gimmick to get more pound notes out of our pockets trying to convince us that the edges are the same compound as what valentino rossi use to have for his moto gp bike. both tires are rated highly online for durability by retailers due to having dual compound casings, hard in the centre and supersoft on the edges. any real life experiences from similar bike owners would be greatly apreciated. please note i do aproximately 3000 miles a year touring and approx 2000 miles having fun and would hope there is a tire combination that could exist that only needs replacing at the beginning of the biking season and not towards the end of it as well look forward to some feedback on this matter regards steve

many thanks for your swift replies, it does seem to like these reasons could be why the problem has occured. hopefully when the weather picks up i wont have these problems. i changed the spark plugs today as well good job really because they were looking a bit second hand upon examination so would have thought this could also be contributing to the problem as well. once again thanks for your swift replies it always helps to have independant advice.

hi im new to this forum but wondered if anyone had any idea what the normal engine temperature should be on a yzf 600 thundercat 1998. the only reason i ask is that last week i took mine up to scotland and have never used it in the cold before but normally the gauge reads about 60 degrees c but when i went up north it dropped to about 40 degrees c and started missfiring. all the lads at work say there bikes are normally running about 75- 80 degrees c and dont fall much below this when on the move. when the temp on my bike drops it starts to missfire but when i stop and the temperature rises it stops missfiring. my suspisions lie with the thermostat or lack of thermostat but wanted to check with you guys first in case it is a common problem. any help would be greatly appreciated in this matter. kindest regards steve
