But, ocassionally the thing still feel's sluggish through the midrange
, moment's later it flies.
I'm baffled again, just as I thought I'd found the cause of the problem.
Went over to the Yorkshire dale's today, with the TPS disconnected from the carb's, and altering it's position from time to time.
About 1/3 open the bike struggles through midrange.
With the TPS about 2/3 open the engine run's better and stronger, with a little kick at about 8ish.
Bingo, found the problem (again).
The first good stretch of open, dryer road, I gave the bike a 'good bit of welly', next thing, the bike loses power in the midrange and goes all soggy again.
Bugger.
I've since been playing with the powervalves, disconnecting the powersupply and setting the pulley in different position's.
Result's;
1; midway, bike surges at about 5500rpm, feel's very strong, v. noticably kick at 8ish, run's out of puff at about 10500rpm.
2; Hi, Bike feel's ok low down, through midrange feel's exactly like it does when it loses power and goe's all'soggy', twisty road's so couldn't be botherd waiting for power to come in!
3; Lo; Bike feel's strong low down and through midrange, very usable, run's out of puff at 9ish.
I'm now wondering wether my TPS AND p. valve motor's dodgy.
Is there any thing to look for inparticular inside the servo housing when it's in bit's?
Funny how thing's are fine for hour's on greasy little dale's road's and suddenly goes AWOL when given a bit of stick.....
Powervalve's move fine when you pull up and blip the throttle.
Thanx,
Regard's Phil
Sorry for ANOTHER essay...
