Rolling Road Dyno Day - John Sleath, Doncaster

I can highly recommend a John Sleath session having put my Tiger on his rolling road a couple of weeks ago. The car was running well before the session but after John had rejetted the carb & tweaked the timing the car really flew on the 70 mile home run. Next stop Pau!

Give it a go, he knows what he's doing & he's a really nice guy with it!

Lack of real interest and so was postponed, with a date in the future yet to be agreed.

I'll put your name down as an interested party

Hi Tony, I'd be interested too, should have the 289 rebuilt in a couple of months

Old thread I know, but managed a quick trip to John Sleath a few days back. Who once again worked his magic on the Tiger, and ahead of the Cannes/Monte Carlo epic Euro trip - he is highly recommended!

Youtube vid I have loaded as this time we had a run with the exhausts fully opened, turn up the volume and watch in full HD

Took my Tiger to John Sleath yesterday (22nd October). It has a mildly modified 260, see earlier in the thread for details. Made 220 bhp at the flywheel at 5000rpm, John did not run it any higher and I hardly ever see 5000rpm! But had 260 lb ft of torque from 2300rpm to 3600rpm and still had over 240 lb ft at 4500rpm. Fueling was rather rich at the bottom end but with a change in metering rods and jets was much improved and acceleration is now much quicker. Well worth a visit.
