Just picked my barrels up this morning had a fresh rebore to 65mm with new pistons ect and a tidy up of the porting so they match,, rull race spec now so, my question is won't be a while few months or so before I build the engine,, so that in mind should I oil the bores or leave them dry as is not wanting them rust or something or will the oil soak into the bores over time?, any suggestions 👍👍
Ha ha already under the stairs mate but will she who must be obeyed smell the oil coming from the magic box that's just appeared there is the question lol is it worth the,, anth wots in this box under the stairs?? And why does it smell funny,,,, question with the undoubted verbal abuse to follow,,,,,, 🤔🤔🤔🤔🤔. YEP LOL
cheers mate ile oil em up and just say we'll the voices said,, hun
Ah just the man Mr arrow,,, as theses barrels are a bit more than slightly ported willprobably be sending you a new oil pump from Mr norbo when I sort it for a 31k ypvs will it require modding and I'm not sure wot carbs Ile be running but prbs not standard, was the oil pump question I was clarifying,, as your the pump man no one better to ask 👍 if that's OK I mean,,,
Ah I get you now cheers flames mate they are a bit sharp all my guy said was check the gap with the valves fitted against the piston so they don't catch the rings said about 1mm gap should be fine I'm presuming the valves don't go near the pistons unless your getting close to 65.5to max 66 mm but I'm at 65 so he's probs being carful
Sorry bud I don't know about the powervalves, I have a motor but haven't done anything with it yet. I guess they would need matching to ports.
All the windows in the cylinder will need to be chamfered so rings don't catch. Some places do this with a bore, some don't. I can't see from pics if yours have been done.im guessing not as this has been highlighted.
Cheers flames, Steve,, can't really see from pics so had a quick look the inlet and exhaust are fine it's the little ones on the edges I think looking at them he's ported them and then bored them as the little ones are slightly sharp on the edges so as said ile file the edges of smooth another thing learnt today cheers guys 👍👍👍👍
Well sat for a hr or so this afternoon in the sun and took the filetothe sharp edges in my ports on the barrels I had rebore, and happy no sharp edges to the touch with the old finger measuring tool,, cleaned them oiled them for the second time wrapped em and put them away for later date,,, wot a way to kill an hr 🙄🙄🙄
