Hi all.
Hope you are all well.
Now cracking on with the engine break down and the cylinder head is off after lots of wd40 and a bit of patience to remove the two well rusted cylinder head nuts that sit where spark plug 2 and 3 are
Also I now have a firm plan of the changes I would like to do and want to do the following.
Take the engine up to 460cc with a big bore piston kit (Possibly Yoshi even though it is a tad expensive)
Fit a Yoshi stage 1 cam (again a tad expensive)
Have the head ports and flowed to suit Keihin CR 26 carbs and basically restored to as new to suit the stage 1 cam
Uprate / modify the oil pump to suit a GL1000 oil pump rotor
Do a complete rebuild of the bottom end seals bearings replace both primary and cam chains and replace any other stuff like the primary drive Cush rubbers, new clutch plates and springs etc etc
Dynatech ignition
Also planning to fit an oil cooler to ensure that the oil temperature is better controlled as all the above changes will increase the oil temp. And it looks cool too!!
Lastly (and as mentioned earlier) fit a set of Keihin CR 26 carbs. But with these I will also need to modify the bottom of the tank for the required clearance.
Very happy to complete the engine build itself, but wondered who to trust / outsource the work to like the re-bore and head work?
Ideally would like to deal with one company rather than use one company do the re-bore, and another company to do the head work etc.
Was looking at D & M Engineering and wondered if anybody here has used them? Or if there was any other trusted recommendations for other companies / people in the UK.
Many thanks to all in advance.
Very best wishes Al.
