Same hot start problem

I'm debating if the reason my bike is hard after gas fill ups may be the R/R.
Has anyone had any positive experience with easier hot starts after this change?
I've tried the easy stuff now on to the difficult!

Do you have an MF battery installed?

I have the same problem. I'm certainly no expert here but it dsoesn't seem to be a "battery" issue as the battery provides plenty of juice when the bike is cold. Only have issues when the bike is hot.

R/R relocation seems to be the answer here but nothing to prove it. If it is, where can I find a step-by-step procedure on how to do it and what I'll need?

Thanks.

You really need to answer that, as wet cells are notorious for your symptoms.

I doubt seriously it is the R/R, as , the bike seems to be running and will start (eventually)

Have you tried adjusting the pickup coils???

Many say this did the trick when even after getting a MF battery they had problems starting the bike when it was hot.....


You have iridium plugs too of course, and the bike is stock...and you use Seafoam religously right????

There really isn't any step-by-step instructions for the RR relo that I have seen. However, after having done it myself I can tell you it is pretty simple. I used some 1 1/2 in bar stock from Home Depot, a U-bolt, and some heat shrink tubing. I marked and drilled the bar stock (2 holes for the U-bolt and 2 for the RR), put the hat shrink tubing on the U-bolt to protect the finish on the frame, and mounted the bar to the left side of the bike. I have a picture in the gallery of the end result. Others have used the top bolt of the passenger foot peg to mount the flat bar (only 3 holes to drill in this case). You can also contact Bulldog to get one of his brackets which simplify the procedure even further! All you need to do is bolt it to the bike; no cutting or drilling. If you do a search on RR relocation there is a good deal of info on the site.

x2. I thought the MF battery thing was bull****. BUt, I had the same problem, so I tried it. Only thing that makes me mad is I didnt do it sooner!

The MF battery thing is for real.

I put a gel cell battery in my bike right after buying the bike. It still had a hot start issue. The R/R relocation (with Bulldog's kit) greatly improved it but it is not entirely eliminated. My next step is NGK iridium plugs. After that, I will just live with it being a little finicky to start.

I haven't been following your posts on this issue, (if you've made any), so I don't know what you have or haven't done yet, but I just found some info on this, past changing the battery, in the Verses. Hope this helps.

Just follow this link- https://www.vn750.com/forum/showthread.php?t=1167

In that link is mentioned doing the "pick up coil mod", it seems find out what that is and how to do it is a little more challenging. While searching for it, I tried "pick up coil adjustment" and still haven't found out the what or how, but did see somebody else mention their bike starts great now, hot or cold, since they did it.
