I'm sure that we have all read about the good work that arrow does with LC / YPVS oil pumps, but I just wanted to make sure that people are also aware that he does equally as good a job on the single output versions. I recently restored my DT125LC & suspected that there was an issue with the oil pump, so sent it to Gary following the numerous good reviews that I have seen. I can only confirm what a fantastic job he does, kept me up to date & told me what was wrong - I had no oil feed below 1/4 throttle, which would have been a disaster on a rebuilt engine. If you have a restored machine, don't take the risk - send your pump to this chap - for the sum of £45 including postage, you will get it back looking & working better than new. I will be sending my YPVS oil pump over the winter, no doubt about that!
