Mounting a Hsr-42 carb..

Recently ordered a hsr-42 :busted:


I have read that it is som problem mounting it. So, if anyone could post at pic, or two, on their installation, I would be really happy!

Edit: It is the xr650r I'm talking about.

hey mate

they require adapters to fit the XR-R

I took mine to the machinist and they did up some really nice looking adapters for about the price of the sudco ones, but doing it much faster for me.

You then need to completely rejet it.

Good starter settings for a stock bike uncorked:

22.5 pilot - 3 turns out

1.2 air jet

9DJy01 needle - 3rd clip

Y4 needle jet

137.5 main jet

#50 nozzle from HSR42 - firing at the needle

this is working well for me, but may not be perfect yet.

      Changing out my fork oil on a new to me 650l. What's generally recommended for stock springs and valving?

      So I don't seem to find my specific issue so here I am asking. 
      I have a 1997 Xr600r. It was recently re-jetted and has ran really well ever since until more recently it has begun to have this issue.
      Everything works fine. Kicks right away, nice and easy. Runs great, sounds great, purs. But when I'm downshifting and slowing down to a stop, if I let my hand off the throttle that's when it just dies. I found that I can counter this by lightly holding the throttle as I down shift (so I'm revving quite a bit during downshift).  But it hadn't done this before. 
      The only thing I've done that I suspect may have been an issue on my part was when I pulled out the engine to change the valve cover gasket and upon doing so perhaps when connecting the carb back to it, I may have missed something or made a crack in the boot? 
      Any ideas? Thanks

      Hello all,
      There's been a lot of talk about how to register a dirt bike in states that don't allow it.
      I just moved to North Carolina and for the first time in my life might be able to afford a bike. I've been dreaming about an XR650R for a long time, but they're not cheap. Plated bikes seem to be more expensive too. So here's my question, has anyone tried to plate a dirt bike by adding all the necessary features and having it inspected as a custom bike? Anyone know of another way I can plate an xr650 in NC?
