No not jumping because of revs opposite on the over run ie when I shut the throttle the crappy Suzuki Bakelite strip in the cam cover never worked properly hence pops put a Kawasaki z1 guide wheel in the head

i've raced a gs1000 yoshi for a few years and have just built another, Rickman gs1000 for a couple of road races in Belgium this year 120 bhp is a big jump on a 47 year old engine, mine is sticking out 127 at the tyre and that took some real effort, big valves, cams, 1085 cc ported head, crank aligned, welded, new bearings everywhere etc, etc, etc straight cut primary gears, jaygui race exhaust, we have also started to encounter a few problems with the cam chain jumping on overrun, this was exactly the same issue pops yoshi had a 130 bhp so unless you are going to race it, set you sites a bit lower, say 100 bhp 1085 cc, new bigger valves, cams etc, nice set of new 36mm rs flat slides will make it much nicer to ride, all the old carbs are knackerd and worn out now and it will never run nicely, race bikes are a lot easier to set up ie flat out or off

Managed to spend a bit of time on the rickman over Christmas my current job means I fly to the USA 1 week a month so I contacted hindle directly, they are based in Canada about their race exhaust to fit gs1000 bought one and shipped it back with me really helpful company took about 3 /4 weeks to make the system for me, I also learned the difference between the printed version of a canadian and American dollar ! we were both a little concerned the link pipe would need modifications to get around my swing arm brace but it fits perfectly, not sure I like the exhaust hanger that came with it but this works for now sorted out the brakes now with the new Nissan semi radial m/c and Richard hocking cobra supplied the new braided brake lines

Hi paul and OSs collective good to see you all over the weekend throughly enjoyed myself as I was unloading the bike last night I happened to notice some extra stickers on the gs with an ice cream logo Don’t know why Paulm but your name immediately popped up in my head

The suz gsxr 750 2004 to 05 will fit the output shaft of a gsxr11 1127 adjusted the stack I did have to guess the primary spring tension of the diaphragm but you can get these 10 kg increments so may have to have a play with this and the secondary spring

Hi sorry bit slow answering, work trip back out to see the septic’s engine is back full fat Yoshi, cams, carbs I am using the dual inlet tmr mjn 41mm in the Harris, Yoshi covers, ti bits in the valve train, new cam chain, shells, Carrillo rods, stm slipper clutch, big valves, big head port, new oil pump, the lot, the original covers have been cerakote to match the Yoshi covers too I have also attempt to bribe, cajoled, cried and generally pestered dupesunc into helping me as the plan is still to race it and he has been busy designing and printing carbon secondary oil cooler air intakes anything that will help with quick wheel changing is a big plus As I hate it, some time ago Gary was able to help with some details of the f1 endurance front fork brace and my swing arm is off the mark at RCD to have the endurance/ retained wheel change modification added other than that I am trying to finish the rickman, usual story too many projects

Update with a few more pics and colour change few small jobs to sort, I want to replicate the rickman style gear and brake levers but not the weight and complexity so copying but in alloy also the front master cylinder is very tight to the fairing so that need a rethink made a bit more difficult as I can’t use a radial due the class race rules tucking up the exhaust link pipe is also on the list and then dyno and testing

You can never have too many Harris’s duncan

Oh the joy of trying to find something to lean your bike against that looks very cool

yes 2 for bike for me

nice blue ti headers already looking forward to seeing it in the flesh

Ohh that’s going to be challenging for you Duncan

I can see you had to get the right size not much else is going to work
