check your hoses, mine did the same, dan from the forum had a look and thinks it could be the hoses on the engine...

hello me m8 , good to see another gen 4 vert owner B) .

mine was flat when i bought it, ive ran two 1ltr bottlesof STP injector cleaner throught the last 5 full tanks, cleaned the throttle body, its had a service and a rolling tune - its gained another 10 mph top whack and runs absoluteley fine.sounds loveley since the new full exhaust and cone filter.

i would reccomend a rolling tune, they will find any flat spots and advise you, it might be worked out anyhow a good tune is worth the £40 ish.

im changin the leads and dizzy cap as they are original and have 1986 stamped on them!! that should give at least another 1 - 2 bhp.

laters peeps, let me know how you get on :thumbsup:
