Re: Question about yanclone, enfield and longer mainshaft
Well, i keep thinking about 2 'problems 'with placing the engine in the middle.
1- the support of the inner primary; Since the gearbox shaft comes in a bush-bearing, the engine has to be placed perfectly in it's place, unless you can drill mounting holes yourself.
That the strain from the gearbox shaft is being transferred over the aluminium(!) case lid doesn't sound very sturdy, but connecting it with 4 bolts via an adaptor plate to the engine? Won't the holes wear out very rapidly?
..In that case, maybe it is better to place a ball bearing in the front of the inner primary, which transfers the strain to the engine crankshaft. This means the engine has to be lined out even more precise.. and what happens if the engine warms up?
2-The yet to produce subframe; i have learned it is important that it connects with the lower-hind frame under the gearbox, and the gearbox ground plate has to get support to prevent rupturing- as seen in a former topic of mine, 'subframe rupture, need advice'.
The priceparts-weld in- subframe is based on tubes and that's nice to abosorb vibration, but again seems to lack support for the front frame tube and half the engine weight is set on the swingarm brackets, via an V-shape to the central frame tube..
Seems not ideal or even inviting more ruptures.. Maybe add/weld on a gearbox plate as provided with the self-made U-shaped subframes?
Any thought will be welcome!
i want to do it right this time..
