the subframe part1 is on the frame

Today Jeroen welded the subframe. It fits nicely between the frame and side panels. The right engine cover sits right behind the side panel. This Friday I'll try to make the bottom part of the sub. A triangle from the center stand bolts to the sub.

drawings for the subframe and swing arm CH250 Spacy/Elite

I'm making drawings for the subframe and swing arm by making templates on paper from gaskets and pin gauges. After scanning them into the computer I use Adobe Illustrator to make dxf files.

working on the stretch subframe CH250 Spacy Elite

I'm working on the subframe to determine how long it needs to be. The clearance between the wheel and the spring was practically zero so I made the offset 45mm instead of 41mm. I'll be making a 4 mm spacer between the hub and the wheel. i hope I won't have to adjust the frame for the cylinder head.

Deep purple beauty in the workshop!

Yep, the time has come. The CH250 Spacy/Elite has his big brother in the workshop. It is a 1994 Helix with a beautiful deep purple colour is very good condition.The overall state is pretty nice, it only needs an engine check and a new clutch. It has 48,000 kms on the speedo.

I plan to coat the grey fairing in the same deep purple color, drop it 5cms and an XXL longshot exhaust. Plus a new matching upholstery.

I'm a happy man...

the CH250 engine is back on the frame

I put the engine back on the frame to start working on the subframe. It needs an offset of 41mm. With the use of templates I'm making a drawing to build the right side swing arm. 
I am using the ComposiMo Yamaha Zuma stretch as a starting point. Credits there.
I'll have to remove some parts of the frame in the back, because I decided to go for a 170mm/ 6.7inch stretch. Pretty long but it can use a serious stretch visually. It will be trial and error to find the right length.

getting somewhere with the CH250 Spacy Elite hub

Today, I did some work on the hub. I made a removable center piece, so you can fit different rims.This one's inside diameter is 62mm.If I want to change it I can change the center ring.I have to find M10 lug bolts, not very common apparently. The second option is to use long M10 press bolts.Or make the holes larger to fit M12 bolts.

The next thing is to fit it on the frame and see what the offset will be.

Progress on the Drum Hub Honda CH250 Spacy Elite

Today I made some nice progress on the drum hub. It took me a while to find the solution.Make a whole new aluminium hub and have a spline bushing and brake line made to fit, or use the old drum hub and extend it. 

I opted for the second because making a new from scratch will take up too much time and for me it's about building it to drive it.

Left the shaved drum hub, right the aluminum part with a 20 degree angle for centre fitting.

 I bolted both parts together and permanently Loctited 638 them together 

 four countersunk bolts

 on the axle I turned it with the right dimensions. The total drum hub needs a 76mm width to take the 225-10 rim

Still have to drill the bolt holes  and make an insert in the centre to fit the right swing arm.
