Yeah, it's not something I want to do. It's been a very fun project with some ups and downs.
It's a shame I don't have any property. Trust me, it wouldn't be going anywhere. I had the Honda FL 350R Oddyssey and people preferred driving the Yerf over it. I really feel like we found a winner with my set up. Once I installed the TD heads with the valve springs you got for me Tom, all my valve problems went away. I cannot stress enough the beating this buggy has taken and keeps on running strong. My Uncle had a Hammerhead 250 at the family reunion and couldn't shake me. I was a hemorrhoid on his ass he couldn't get rid of.

I'm sorry to say the buggy has been sold.
 It was a real fun toy and project with many ups and a few downs, but I learned a lot from it and this board. I want to say thank you to all who helped me through this project. What a great group of guys this board has. Hopefully Brian the new owner comes on and keeps everyone up to date on this as he and his daughter seemed pretty excited to let 'er rip. (Even though this is supposed to be mom's buggy) Thanks again for all your help, and when I get some property to play on again, I will be back.

And just for ease of finding if anyone is interested seeing what gains can be had from certain modifications, I'll leave this here.
Post #11 in this thread lists many upgrades and the results achieved. http://buggymasters.com/forum/showthread.php?t=2670 Sad to say I never recorded any more info after my latest performance upgrades. I'd be curious to see where she ended up with the current set up. The KNM performance pulley really did give a noticeable boost in the bottom end take off (0 to 300' speed) and the large valve head with TK exhaust might have helped to utilize a larger slider weight for more top speed. I actually bought heavier sliders but never installed them as i was extremely happy with the present set up and didn't want to change a thing.

GY6 valve job going downhill
2006 YerfDog Spiderbox 3206
Picked this up about two years ago for 800, was garage kept and had meticulous records and only two owners. Got the front suspension fixed after I sent'er a little to hard on some washboards 😂, replaced original front end with a full BDX HD front end (bulkhead, A arms, knuckles and atv front hubs). Now to the new issue..valves/top end power loss. GY6 157qmj: Checked the valves which had almost no gap (way less than .002 on int & really tight .002 on exhaust. .002 is the smallest feeler I have so idk exactly where the int was). Set valve gap to int-.004 and ex-.005 but, I lost 2mph. So, then I set int-.003 and ex-.0045 but lost another 1mph. Before I adjusted the valves I was getting up to 29.5mph but, after first adjustment I dropped to 27mph... Then to 26mph after 3rd adjustment. Though I have a picked up low end torque a noticeable amount 🤷*♂️ I have a jet kit coming as it feels like she is struggling for fuel at the top end. I get up to about 8500rpm and it drives nice no struggle but push to 8600-8700rpms and it feels like she's gasping for "air" (or fuel) ie. Lunging/pulsing at wot. 🤷*♂️🤷*♂️🤷*♂️ Any ideas? Am I on the right track? Am I missing something? 🤷*♂️🤷*♂️🤷*♂️ Help- Please and Thank you |

Though, It still seems to be lightly gasping on top end near 9400+/-rpms BUT, it seems to be rich at ideal as it holds floats between 1580-1620rpms and about every 200-300rpms it spudders/"misses" one firing. Sounds like an extremely light backfire *pop/puff* 🤷*♂️ any ideas |
