a lot can be said of a person that shares their talent with the world, expecting nothing in return. Thanks.

Never had a problem knurling forged pistons bike done that way 25 yeqrs ago and does not smoke...runs great

[@TatroMachine]

yes it does work but not all pistons can be knurled. only big full round pistions with no internal supports can be done. tatro

[@L2fish]

I'm having trouble so I go right to your videos. My 85 hasn't run in 5 yrs, been sitting in a shed. Got it running. Have some smoke. Checked compression, have 70 on the front cylinder, 80 on the back. I suspect worn rings or worse. Idles fine, pulls fine, just smokes and wet pipes.

I love listening to Tatro talk about his passion n with knowledge!!! 😎

[@Richard-yq2mm]

Your vids are great, and knowledge level off the charts. The Sportster iron head is my favorite bike. Had a 1976 XLCH I bought as a true basket case in 1981 (old fart). Had a local shop rebuild it. 30 over, new valves, pistons etc. 1-3/4" drag pipes (pipes were mine). In 81 the cost was $2,700 for machining & new internals. Ran perfect and started on the 1st. kick 9 out 10 times, witch dumbfounded my friends. I miss that bike everyday. hope to get one again. Love that Dog. what's it's name?

[@edwardkesock216]

love your vids

Building a Ron Trock Panster and Shovster right now. I am working with Ron's son Ron Jr.

[@TatroMachine]

i don't know what the big deal is with running the big twin heads on a sportster. they run faster with the sportster heads on them. i was running 125mph at the drags and over 150mph at the lakes with a 90ci kickstart 1957 sportster motor back in the early to mid 90's. i rode it on the street too. i was right behind the pros at the drags and they all had evos. tatro

[@edwardkesock216]

whats the quickest way to gain horspower on a 1980 ironhead 1000cc stock bike just picked it up really want to have someone do a onceover the bike but iam just curious its my first ever motorcycle and its a harley ironhead its been customized by the guy i got it from no turn signals 12inch aps single seat custom paint but the paint job isent good stand back 10feet looks better got the bike for 1300 bucks and it runs but does need a little work clutch adjusted but i like it and for the price i hope i did good

[@TatroMachine]

38mm mikuni carb, dyna 2000i ignition and a good set of 1-3/4" exhaust pipes. p" cams or some mild aftermarket cams and some port work would be next. tatro

[@sprocketsouden6370]

do you have any video of porting an ironhead? I've watched the aluminum head porting videos and wondered if it's any different. I'm working on an early 84 1000cc sportster, any tips?

[@TatroMachine]

i have a set coming up next month to do. i think i did the 1961 xlch motor? look in the playlist. tatro

[@bsteendam]

hi tart love the vids, just bought a 79 xlh 1000 electric start, wondering if its worth putting universal oil filter on? as doesn't have one from factory, will it cause complications with oil pump? thanks from Australia

[@TatroMachine]

harley had one on the left side lower front motor mount as an option and the aftermarket has them too. you will see it on some of the xl's i work on. tatro

[@IMKINDOFABIGDEAL13]

I have a 1980 xls 1000. It was stolen from me and I ended up getting it back years later totally trashed. I am now building a rigid bobber with it. The motor needs an educated person to go through it and find out what parts are missing and put it back together. If I was to ship it over what would be a ballpark figure to do something like that like low price and a high price? I am in the Portland Oregon area, not sure where you are.

[@rob53chevy]

Who makes that particular stroker kit because I have the same thing but I’m having a very difficult time iding the parts?

[@TatroMachine]

did you try tatro machine? i hear they have lots of parts. tatro

[@bsteendam]

Hi tatro! Love the vids! I've been looking all over the internet and can't find much info on 79 xlh 1000 sportster in general. Just wondering with the rear caliper is ment to have movement up and down or is it ment to be fix to the swing arm bracket? Thanks tatro

[@TatroMachine]

the stock caliper is a floating caliper. that is that it slides side to side as the pads wear. the up and down movement means that the caliper is worn out like they always are. the front flt caliper is the same from 1979-83. look at my single cylinder race bike and how i put a wilwood racing caliper onto it. the bike is a 1979 xl. i picked up over 10mph when i switch to the race caliper. tatro

[@bsteendam]

thank you heaps tatro. hope you don't mind the questions.

[@cfreeway8385]

This build is very interesting but I can’t find the episode where you machine the lead from the flywheels. The melting and pour of the lead was great! I want to see it finished if possible. The Tatro Way. Did you get that episode on video?

[@TatroMachine]

watch the playlist, the videos play in order. tatro

[@dwaynesellars4196]

What would make a 78 shovelhead smoke sometimes and not other times. it does it only out of rear cylinder.

[@TatroMachine]

rings. tatro

[@kroz2310]

if the starter is sticking out past the cam & sprocket cover its an 80 sporty if it tucked in its an 81. i had an 80. 79, 80, 81 r terrible yrs for sportys. at least it wasn't that fugly 79 wit the rear master cylinder at da top of the front sprocket cover w that funky shaped rear pipe.

[@roccomalachi7329]

tatro sir if i may ask 79 gear box Lshift adaptable to 73 rside shift.

[@TatroMachine]

it can be done but i don't know why you would want to. tatro

[@ckelley63]

Cameraman sounds like Quazzy Moto Lol!

[@GaryLordsWayMinistry]

Wrong that was below the rings it was in the block, something was coming loose in the bottom end and coming up from the crank and cams could have been bearing material. Not the breathers on the carb or the crank in my opinion.

[@roccomalachi7329]

I'm keeping it right side shift but all I have is a left side trans

[@wolfeyes9357]

Knurl the pistons
