    4-tec engine rebuild question

    I am in the process of rebuilding an 05 rxp 215. I have a good set of cylinders from an 07 rxp sitting around that are ready to be used. My plan was to purchase a oil jet from green hulk to put in the 07 cylinder block so it has the correct oiling for the 05 head and rocker shaft. I found out today that green hulk is sold out and rotax racing has discontinued the part. I know that I can use a 2006 plus rocker shaft to effectively block off the 2 additional oiling holes in the 04/05 head. Is there any reason a person cant tap and put set screws in the 2 additional oiling holes and use the 05 rocker arm?

    thanks in advance.

    I have a trashed block with an oil jet in it if you're interested.

    Thanks for the offer. I actually have a block with the jet in it. Is there a secret to getting it out without destroying it?

    personally I would just take a die grinder and carefully cut it out since the block is trash.

    it doesn't matter about the oil jet since it wont fit in the block anyways. 06+ oil hole is smaller and the jet wont fit in it.

    well, sound like 06+ rocker shaft needed to me.
