imago Posted December 21, 2023 Author Posted December 21, 2023 Rims are done now, exactly as I asked them to be. i.e. make them as shiny as possible without removing material to get rid of any deeper marks. Pays dividends using someone who knows what they're doing and listens to the customer. Arm will be done after Christmas. 4 Quote

imago Posted December 22, 2023 Author Posted December 22, 2023 I was talking to the bloke I got the pistons from last night, and he has photos of a Saxon race bike which has the same wheels, but although the centres are identical the rims are one piece carbon. Quote

imago Posted December 22, 2023 Author Posted December 22, 2023 Right then, deck height, squish, compression ratio and capacity checking time. 1 Quote
imago Posted December 22, 2023 Author Posted December 22, 2023 (edited) The engine that the block and pistons came from must have been insanely close to the edge. The squish is purely head gasket thickness. I think a base gasket adjustment may be in order. By my reckoning that gives me 11.5:1 compression and 1165 cc displacement. Edited December 22, 2023 by imago Had to remove close up of the piston. Quote
DAZ Posted December 22, 2023 Posted December 22, 2023 If it was a race bike my assumption would be that it had long enough duration cams to reduce the dynamic compression to an acceptable level 1 Quote

EFE base gaskets are steel ...earlier models are paper ... i always use EFE one's on any GSX motor 2 Quote

I need to get the big valve head off of the engine in the ET, check the compressed gasket thickness and then double check what I have squish wise. 19 minutes ago, DAZ said: If it was a race bike my assumption would be that it had long enough duration cams to reduce the dynamic compression to an acceptable level I haven't sorted the cams for it yet, so I need to get on with that so that I know where I'm at with lift and duration. 1 Quote
imago Posted December 28, 2023 Author Posted December 28, 2023 Right, moving things on a bit and I got an xr55/Slabby seat unit to try courtesy of @SFC(it's a seconds unit for chopping purposes). A bit of cutting and trimming at the skirts and I'm liking the lines. I'll take some more off once I get the arm and wheels under it so that I can see the general shape of the bike better. Don't want to cut too much off until then as it's a bit more difficult adding than taking away. 9 Quote
clivegto Posted December 29, 2023 Posted December 29, 2023 Does look good but for me it just needs lifting a touch at the back 1 Quote

imago Posted December 29, 2023 Author Posted December 29, 2023 It's just sitting on the rails as it is. The final/correct position will see the very front of the seat/tail come down, the back up a touch and the back of the tank down about 5mm. Basically the top of the tank and the top of the tail unit will be a straight line. I need to get the wheel and arm under it before I go too far down the lining things up road though as it might not work so well then so I don't want to waste time and effort only to in it later. Once that's done and I've decided between a combined electrical tray and mounting or two separate parts I can make it/them. 1 Quote

DAZ Posted January 4 Posted January 4 Indeed it does , it'll look classy with that dark grey , I've no doubt it'll be rolling before long 1 Quote
imago Posted January 10 Author Posted January 10 Time to remove the now run in big valve head and 1168 Wiseco big bore. The head's going on the Dresda. Big bore on something eventually. 2 Quote

Havoc Posted January 12 Posted January 12 I'd get tyres on those delicate rims sooner rather than later, give them a bit of protection 1 Quote
imago Posted January 12 Author Posted January 12 All coming back off once I've got my measurements for spacers etc. Lots of trial fit stuff to sort out, then I can get some boots on them and work out what I need in the way of discs and sprocket. Quote
Havoc Posted January 12 Posted January 12 I get that, but those rims with tyres on even old ones that will be replaced, will be much safer in the mean time. Quote

I'd suggest putting old tyres on and off would risk more damage than being careful as they are. Fear not, they'll come to no harm in the couple of weeks until they get tyres on. 1 Quote
