Dyno readout of Mike Hamiltons 850 with JS parts

In response to above post.

See Dave Watson's Norton below. Comparisons were made before the JS light weight pistons and valve train - lightweight radiused lifters etc. The earlier heavier pistons held down the RPM range. Although the bike was not dynoed, there was a significant gain of over 1000 RPM added when the new lightweight JS parts were installed and power was up. The motor also ran smoother. It won every UK National classic 1300cc race in 2012 against multicylinder jap bikes, British triples and Westlake 8 valve motors.

Dave Watson's Norton big block performance using JMS kit for eager hi-ish rpm tolerance is music to my ears Jim. I've had a bit of cash wind fall so am spending on stuff for a portable-sharable road going dyno-data logger to pass around and see what the various figures show. If any one not as digitally dumb as me has insights skills in digital doodads- along the lines of the "internet of things" ping me please.

WZ507, didnt get a printed sheet this time , but as they have it on record I will get a print out at some stage and post for you.

Alan, I dont think the lap times are much good to anyone on here most of the forum members dont know how to pronounce our Maori names let alone know where the tracks are.
I would have to list PB's from each race and meeting , track conditions, wet or dry, hot or cold so too many variables, once again meaningless as a more skilful rider than me could take lots of seconds off my laptimes on my bike as I am fully aware. And compare the laptimes to what?
I was sharing information with you guys , not trying to be the most powerful or fastest bike out there. If I had 60 RHP there would still be sceptics!!!
I think 4th in class for the year after 2 rounds of 6 rounds shows the bike is reliable amd more than capable, riders skill, (as in me), better than average to good, and thats only my opnion.
Pass the hat around for some dyno testing funds and I will gladly take it around the country getting different appraisals and readouts!!!
Average them out, then post the results, even better ship it to Jim Comstock for a test.
Regards Mike

That's likely true, but JS parts are proven so not hard to believe the data. Gains in HP and a much smoother running engine with less vibration...which some of us street riders can benefit from. People want to shoot holes in everything here and argue every individual word posted. It's really too bad. Good luck with your bike on the track...should be fun to see how it performs.

We missed you at Hampton Downs Mike, Once I passed the Harley and the Triumph 750 I had no one to chase who was not out of sight :mrgreen:
Alcotrel, Steve Bridges manages 1:16 on his 'Commando' short stroke custom everythingie... combination of $$$$$$$$$$$$$$$$$$$$$$$$$$ and talent.
Best the rest of us can aspire to is mid 1:20's

Hi

Dynos are about setting up & noting the difference when making changes (tuning) useful tool.
The race track is the place to see how well your tuning has improved your lap times.
However
At Donnington last year, we had a 3 second difference in lap times on Friday compared to Saturday!! I didn't think the weather had changed enough to make that kind of difference. Never wrote on my notes temperature, light breeze. Just used to say sunny, fine, damp or wet.
The only comparison is against your opposition (mate)

When I was at the Texas Mile the only records broken happened in the early am when temps=denser O2/N2 and humidly helped a lot and later in day the same pilots & craft came in all frustrated-angry-depressed-swearing with longer times lower speeds. Most the heat of combustion expanding N2 & H2O is what makes torque, not so much the by-products combustion gases expansion. A simple G force meter gizmo on bars would be a down and dirty real world monitor of what this and that change does, per the weather at the time too. Once happy with G meter then dyno to get power numbers to share. One part of my Peel hobby will be travel to various dyno's to see the range of readings then toss coin or average out what to believe in.

Hi John, thanks for that, was disappointed in missing the meetings myself, was it the blue Rickman framed Triumph from Gisborne?
I see Adrian went pretty good as well.
When is the next hampton round with the Hamilton club?
